            Bug ID: 59827
           Summary: winedbg: Ctrl-C segfaults 32-bit deguggees in new
                    WoW64 mode
           Product: Wine
           Version: 11.10
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: winedbg
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: Gentoo

Running a 32-bit executable with winedbg and hitting Ctrl-C to break results in
a segfault. Doing the same in old WoW64 mode with WINEARCH=win32 works
correctly. Seems to affect all 32-bit programs.

A working workaround is to send SIGTRAP to the process manually, e.g. `kill
-SIGTRAP $(pgrep test.exe)`.

Reproducible with:

#include <stdio.h>
int main(void) {
    for (;;) {
        printf("test\n");
    }
}

$ i686-w64-mingw32-gcc test.c -o test.exe
$ WINEDEBUG=-all winedbg test.exe
WineDbg starting on pid 0134
0x0000007bfa4686 ntdll+0x64686: movl -0x58(%ebp), %eax
Wine-dbg>c
Ctrl-C: stopping debuggee
Unhandled exception: page fault on execute access to 0xfff4109c in wow64 32-bit
code (0x000000fff4109c).
