Debugger bugs

[Mike Hearn]

Hi guys,

I've got a few problems with various debuggers. Can anybody help?

1) gdb doesn't seem to catch signals to sent to Wine. In a crash, winedbg
is invoked without gdb ever being aware of it.

2) winedbg can't locate files anymore, the paths seem to be stripped:

0x401cdb48 fixup_imports [loader.c:509] in ntdll: movl  0x0(%eax),%edx
Unable to open file loader.c
Wine-dbg>list
Wine-dbg>

3) winedbg won't print the values of local variables:

Wine-dbg>print i
fixme:dbghelp:SymGetTypeInfo Someone didn't properly set ModBase (0x4078ebfc)
fixme:winedbg:print_value ---error

thanks -mike

run the winedbg in gdb proxy mode, this should work fine.

what does 'info share' report on ntdll ? (normally we should get full 
path if stabs support is present)

this should be fixed RSN (for the moment, 'info locals' should work instead)

I'm not sure, I'll check next time this happens ...

Cool. Another bug: I always get a stack dump starting at zero that
contains all zeros (ie the stack dumping doesn't seem to be working)

and a recent fix by Alexandre may also have a positive impact on this
