[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: [e-mail]
        ReportedBy: [e-mail]

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

`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>)

`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?
