Hi Chris,

I have found some more details on this bug.
I have tested with cygwin 1.3.3-2, cygwin 1.3.2-1 and the cygwin 1.3.2-1p1
(with socket patch from egor Duda applied by me) with the same result,
that means the error message occurs with all releases.

On difference is, that with cygwin 1.3.3 gdb could not start any app as already
noted in the cygwiwn mailing list. So the values printed below belongs to
cygwin 1.3.2-1p1.

I have started the app with bash and wait until the error message box occurs.
Then I have attached the process with gdb. GBD say that there are 4 threads.

Each thread seems to have a separate stack and as I looked at the regs and bt
I recognized some things I'm wonder about:

1. Thread 1 has entered main() and has done many application initialisations
and is short before entering the main loop. If I start the app with the
debugger,
main is never reached and there is only one thread in case of error.

(gdb) info thread
* 1 thread 1300.0x794  0x77fb00ac in ?? ()
(gdb) bt
#0  0x77fb00ac in ?? ()
#1  0x77f975ba in ?? ()

2. Thread 2 has entered cygwin as shown
#0  0x77f820f0 in _libkernel32_a_iname ()
#1  0x77e7366e in _libkernel32_a_iname ()
#2  0x77e760c6 in _libkernel32_a_iname ()
!#3  0x6100457a in _libkernel32_a_iname ()
#4  0x77e737cd in _libkernel32_a_iname ()

3. As I reflect on this facts, I imagined that perhaps because of the
lot of loaded dlls there are some rase conditions, which results in a
dead lock or so, but this in only an imagine, because I really don't
know what MS like to tell me with this error message :-)

4. Below there are some infos about the threads. Perhaps you can recognize
something significant. :-)

Regards

Ralf
