[Bug 18628] New: Assertion failure when setting a breakpoint (x86_64 host)
http://bugs.winehq.org/show_bug.cgi?id=18628 Summary: Assertion failure when setting a breakpoint (x86_64 host) Product: Wine Version: 1.1.22 Platform: PC-x86-64 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: dbghelp AssignedTo: wine-bugs(a)winehq.org ReportedBy: sylvain.pasche(a)gmail.com Wine crashes when trying to set breakpoints from winedbg, or when trying to run winedbg with --gdb. I've built wine from git (version wine-1.1.22-51-g85b6189) on Ubuntu 9.04 x86_64. $ winedbg notepad Wine-dbg>b GetMessageW fixme:dbghelp:elf_new_wine_thunks Duplicate in L"shell32<elf>": __stat<7ec53a10-00000032> stat<7ec53a10-32> fixme:dbghelp:elf_new_wine_thunks Duplicate in L"shell32<elf>": lstat<7ec53a50-00000032> __lstat<7ec53a50-32> fixme:dbghelp_dwarf:dwarf2_parse_variable Unsupported form for const value zero (a) [...] fixme:dbghelp_dwarf:dwarf2_parse_variable Unsupported form for const value one (a) fixme:dbghelp_dwarf:compute_location Unhandled attr op: e0 ../../../wine-git/dlls/dbghelp/dwarf.c:1355: dwarf2_parse_variable: Assertion `subpgm->func' failed. Exception 80000101 Then I can continue, but the breakpoint is never hit. When I try to run with --gdb, I'm getting a similar assertion: winedbg --gdb --no-start notepad 0016:0017: create process 'C:\windows\system32\notepad.exe'/0x110660 @0x7ee3d388 (0<0>) fixme:dbghelp_dwarf:compute_location Unhandled attr op: e0 ../../../wine-git/dlls/dbghelp/dwarf.c:1355: dwarf2_parse_variable: Assertion `subpgm->func' failed. wine: Assertion failed at address 0xf7f99430 (thread 0009), starting debugger... Then I see the "Program Error" dialog box. The strange thing is that with the same versions and same OS but i686 architecture, I don't get such assertions. Could gcc/binutils on x86_64 host (i686 target) produce some different debug sections? -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

The issue is that I have the libc6-dbg package installed, and the Dwarf parser asserts when reading the debug information the .so in that package. trace:dbghelp:elf_load_file Processing elf file 'L"/lib32/libc.so.6"' at f7cb2000 trace:dbghelp:module_new => ELF f7cb2000-f7e15000 L"/lib32/libc.so.6" warn:dbghelp:elf_check_debug_link Bad CRC for file L"/lib32/libc-2.9.so" (got ee3d02ac while expecting 60b35a44) trace:dbghelp:elf_locate_debug_link Located debug information file libc-2.9.so at L"/usr/lib/debug//lib32/libc-2.9.so" [...] race:dbghelp_dwarf:dwarf2_parse_variable ctx(0x33ec88,L"libc.so.6"), for debug_info(abbrev:0x5202ac,symt:(nil)) trace:dbghelp_dwarf:dwarf2_fill_attr ref4<0x7d9f> trace:dbghelp_dwarf:dwarf2_fill_attr strp<__libc_errno> fixme:dbghelp_dwarf:compute_location Unhandled attr op: e0 trace:dbghelp_dwarf:dwarf2_parse_variable found parameter __libc_errno (kind=0, offset=2127723594, reg=-1) at ctx(0x33ec88,L"libc.so.6") ../../../wine-git/dlls/dbghelp/dwarf.c:1362: dwarf2_parse_variable: Assertion `subpgm->func' failed. My guess is that the issue is a consequence of the unknown Dwarf op 0xe0. This one seems to be a GNU extension (from gcc-4.3.3/gcc/dwarf2.h): /* GNU extensions. */ DW_OP_GNU_push_tls_address = 0xe0, readelf --debug-dump /usr/lib/debug/lib/libc-2.9.so <1><8227>: Abbrev Number: 14 (DW_TAG_variable) <8228> DW_AT_name : (indirect string, offset: 0x2700): __libc_errno <822c> DW_AT_decl_file : 4 <822d> DW_AT_decl_line : 33 <822e> DW_AT_type : <0x810f> <8232> DW_AT_external : 1 <8233> DW_AT_location : 10 byte block: 3 10 0 0 0 0 0 0 0 e0 (DW_OP_addr: 10; DW_OP_GNU_push_tls_address or DW_OP_HP_unknown) -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

All my programs including winecfg were throwing tons of "dwarf.c:1355: dwarf2_parse_variable: Assertion `subpgm->func' failed" errors.

That's not totally related, but I'm getting lots of fixme messages when the symbols are read: fixme:dbghelp_dwarf:dwarf2_parse_variable Unsupported form for const value one (a) fixme:dbghelp_dwarf:dwarf2_parse_variable Unsupported form for const value two (a) fixme:dbghelp_dwarf:dwarf2_parse_variable Unsupported form for const value erx (a) [...] fixme:dbghelp_dwarf:compute_location Unhandled attr op: e0 fixme:dbghelp_dwarf:compute_location Unhandled attr op: e0 fixme:dbghelp_dwarf:compute_location Unhandled attr op: e0 [...] Should I file a new bug for this? The "Unsupported form for const" message is a DW_FORM_block1 attribute that falls through the switch in dwarf2_parse_variable. The "Unhandled attr op" message is about a GNU extension (DW_OP_GNU_push_tls_address opcode). Maybe this one should just be ignored (or better, ignore all the extensions if that's possible). -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
