proposed patch

looking at the trace (in comment #1) from the bug report, there are several
items that don't seem right:

1)

> 0198:fixme:dbghelp:elf_search_auxv can't find symbol in module

this cryptic one means that dbghelp cannot read in debuggee libwine.so.1 for
getting back to ELF env...

2) in crash backtrace

  1 0x00000003be5cf5cc symt_new_function+0xdc(module=00000000020D7150,
compiland
=0000000000000000, name="main", addr=0x7d001270, size=0x1e8,
sig_type=0000000000
000000) [Z:\builddir\build\BUILD\wine-6.21\dlls\dbghelp\symbol.c:357] in
dbghelp
 (0x00000003be5dc208)

compiland=0000000000000000 is bad :-( (the NULL compiland could stem from
problem in 1)
(BTW it's very likely related to bisect result in comment #5)

please test the attached patch that should at least prevent the crash

3) related to the patchset dbghelp-Debug_Symbols patchset (and why it creates
issue only when applied), I need the both traces the dig further:
WINEDEBUG=+dbghelp with the patchset applied and not applied
