p.envptr is supposed to be filled in by the call to _cygwin_crt0_common
in cygwin_attach_dll. It is supposed to be set to the address of the
"environ" variable in the DLL. It is not supposed to be NULL. That
assignment should actually not even be necessary but the fact that
envptr may be NULL is a problem. Of course, it could just be some
non-NULL garbage too. Running in gdb and getting a stack trace would be
instructive.
Can you be more specific? (I have been using cygwin for a while, but I
never debugged it beforehand.)
I can install gdb using setup.exe . What should I do then in order to
obtain a stack trace?
Grab a snapshot from <http://cygwin.com/snapshots/>. You want the DLL
and debugging info at least.
