problems with dwarf2

[Oliver Stieber]

Hi,
   I've been trying to do some graphical debugging with ddd but the dwarf2 keeps crashing with...

wine-pthread: dwarf.c:1298: dwarf2_parse_udt_members: Assertion `((void *)0) != entry' failed.
wine: Assertion failed at address 0xffffe410 (thread 0009), starting debugger...
WineDbg starting on pid 0x8
Unhandled exception: assertion failed in 32-bit code (0xffffe410).
In 32 bit mode.

I'm also having problems when I try to add a break point from winedbg
winedbg foo.exe
break foo_bar

Exception c0000005

is there an easy way to turn of the dwarf2 code?
