[Bug 28801] New: stack_set_frame_internal passes undefined value into SymSetContext()?
http://bugs.winehq.org/show_bug.cgi?id=28801 Bug #: 28801 Summary: stack_set_frame_internal passes undefined value into SymSetContext()? Product: Wine Version: 1.3.30 Platform: x86 OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: dank(a)kegel.com Classification: Unclassified On my i5 laptop, with ubuntu 11.10, its gcc-4.6.1, and wine compiled with the options mentioned in bug 28753, valgrind complained in d3d9/visual.ok: ... visual.c:7741: Tests skipped: Card has unconditional pow2 support, skipping conditional NP2 tests Invalid read of size 2 at 0x52E44EC: ??? (in /tmp/gl25sfGl (deleted)) Address 0x0 is not stack'd, malloc'd or (recently) free'd wine: Unhandled page fault on read access to 0x00000000 at address 0x52e44ec (thread 0038), starting debugger... ... Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x052e44ec). Conditional jump or move depends on uninitialised value(s) at SymSetContext (dbghelp.c:487) by stack_set_frame_internal (stack.c:82) by stack_fetch_frames (stack.c:238) by dbg_exception_prolog (tgt_active.c:137) by dbg_handle_exception (tgt_active.c:274) by dbg_handle_debug_event (tgt_active.c:354) by wait_exception (tgt_active.c:556) by dbg_active_wait_for_first_exception (tgt_active.c:587) by dbg_active_auto (tgt_active.c:832) by main (winedbg.c:676) Uninitialised value was created by a stack allocation at stack_set_frame_internal (stack.c:70) (Dunno what caused that exception, kind of reminds me of bug 20985, but the interesting bit is the uninitialised variable, which happens while showing the backtrace from that exception.) -- 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.
