Unknown stab type in crashes

[James Hawkins]

Hey,

Whenever wine crashes, I get a long stream of

err:dbghelp_stabs:stabs_parse Unknown stab type 0x2e
err:dbghelp_stabs:stabs_parse Unknown stab type 0x4e
err:dbghelp_stabs:stabs_parse Unknown stab type 0x2e
err:dbghelp_stabs:stabs_parse Unknown stab type 0x4e
err:dbghelp_stabs:stabs_parse Unknown stab type 0x2e
err:dbghelp_stabs:stabs_parse Unknown stab type 0x4e
err:dbghelp_stabs:stabs_parse Unknown stab type 0x2e
err:dbghelp_stabs:stabs_parse Unknown stab type 0x4e

Does everyone else get that too?  Does anyone have info on this?  It's
understandable to output an unknown type, but it does make the
backtrace pretty much useless.  After a couple parts of the bt, the
error message files a couple hundred lines, then another couple lines
of the bt, so I can't see the whole bt at once.  Sometimes parts of
the bt are scrolled up past my history limit.  I don't mean to
complain, but it is hampering debugging a bit.

aren't using something generated on Darwin by any chance ?

Not that I know of.  I'm running Fedora Core 4 test2.  These errors
crop up with a vanilla cvs, but I'll re-checkout everything and build
again to see if the problem has gone away.

I'm asking because those stabs types seem to be emitted only on darwin
Anyway, that's easy to silence them since they're not documented in standard ELF 
format

I have had this patch in my tree for a while now. Should I send it to
wine-patches? Some googling turned up N_BNSYM for 0x2e and N_ENSYM
for 0x4e. Does that ring a bell?

Changelog:
  Silence some unknown stab type messages.

but those seem only created for darwin from what I can see
IMO, we should:
- define the N_{BE}NSYM as any other stabs type
- group them together in the case switch (they are paired anyway)
- and add a comment to explain what it is

I love this title, it gets me every time.

It sounds like a tabloid newpaper headline.
