           Summary: Continuos false SEGMENTATION FAULTS debugging win32

           Product: gdb
           Version: 7.5

SIGSEV on ntdll

Hello all, I have this to report.

I compiled this GNU application
http://springrts.com/wiki/Building_Spring_on_Windows

And I followed all the steps described for a MINGW32 + gdb 7.5 on windows XP
pro sp3 compilation.

The application works perfectly alone, I launch it and works fine.

When I run it with GDB I obtain in order:

SIGSEGV Segmentation Fault into  "ntdll!RtlpWaitForCriticalSection() at
0x7c929af2" 


If I then play , program starts but after a map start I obtain another
SEGMENTATION FAULT into

KERNEL32!GetModuleFileNameA()

You sure Spring itself isn't expecting those segfaults, with __try __except
-like code?

I think no because I'm getting those errors on ntdll and on kernel32 dll...
Really far from spring.exe, the program than crashes out !!

I can provide the exe , but it's very big ... How can we do ?

That does not mean it isn't expecting them.  It may well have __try/__except
around win32 calls, and those may well crash inside those dlls.  Without a
debugger around, you wouldn't see the crashes, as the program would handle
them.

Sorry, I don't personally plan on investigating this further.  You could try
gdb 7.6.  Maybe the issue has been fixed already.

Ok, I personally think that this is a gdb problem.. but I cannot insist further
, I'll switch to Visual Studio.

Than you for the patience :)

I thought about what you said !! In the case you were right than the question
is :
is there a option to let gdb ignore  SIGSEGVs such that   __try/__except
program handle for  me ?

(gdb) apropos SIGSEGV
handle -- Specify how to handle a signal

(gdb) help handle
Specify how to handle a signal.
Args are signals and actions to apply to those signals.
Symbolic signals (e.g. SIGSEGV) are recommended but numeric signals
from 1-15 are allowed for compatibility with old versions of GDB.
Numeric ranges may be specified with the form LOW-HIGH (e.g. 1-5).
The special arg "all" is recognized to mean all signals except those
used by the debugger, typically SIGTRAP and SIGINT.
Recognized actions include "stop", "nostop", "print", "noprint",
"pass", "nopass", "ignore", or "noignore".
Stop means reenter debugger if this signal happens (implies print).
Print means print a message if this signal happens.
Pass means let program see this signal; otherwise program doesn't know.
Ignore is a synonym for nopass and noignore is a synonym for pass.
Pass and Stop may be combined.

(gdb) handle SIGSEGV pass nostop

OK I have many many evidences of my theory . I past 5 days to try and try GDB.

I cannot even attach to the task !!!

Into this thread you can find my experience and many files attach on that forum
 with evidences that GDB have many problems on windows !!!

Also my last compile with another gcc not changed the result !!

here is my forum posts on spring devel website

>From that thread, it all sounds like your mingw environment is messed up.

Setting to WAITING until you finish triage over there.  Please update us on the

This is wat I did !

I restart all the procedure on a WINDOWS 7 x64 and a MInGW fresh install !
The computer was another one and windows 7 was Installed a week ago.

I had less problems with mingw libs but SIGSEGV was near the corner again.
Alwais on that windows ntdll.
