RE: [PATCH] Re: pthread

[Suhaib Siddiqi <ssiddiqi at inspirepharm dot com>]

I still have to build a debug version X with pthread support.
I was runing strace on twm and here is cut and paste from bottom of file.
it seems to be cygwin1.dll issue to me instead of windows managers.  All the
xclients work only windows managers crash/

If you have time...
Run up twm in gdb...

ie 
$gdb -nw twm
run 

and do a bt of the crash.

otherwise put the binaries up (non stripped please) and the source tree
and I'll have a dig around.
