Hello,
I've installed all the Cygwin-1.7.0 packages uptodate, on my
Windows XP
machine.
I do experience a segmentation fault whenever i launch a program
when the
PATH is not set.
When PATH is badly set (but set), nothing happens (and the result
is OK).
See below how to reproduce. When i switch back to 1.7.0-61, the
problem
disappears. On a Windows 2000 machine, the same happens.
Thank you to spend a little time to take my problem into
consideration.

Strange. I can't reproduce this:
$ env - PATHOS=/dqd /usr/bin/date
Mon Oct 19 11:26:46 WEDT 2009
$ env - PATHOS=/nonexistent /usr/bin/env
PATHOS=/nonexistent
SYSTEMROOT=C:\Windows
WINDIR=C:\Windows
You're right, it seems that LC_CTYPE is also involved in this. Please
try under sh:
$ export LC_CTYPE=
$ env - PATHOS=/nonexistent /usr/bin/date
Mon Oct 19 13:12:40 RDT 2009
$ export LC_CTYPE=dummy
$ env - PATHOS=/nonexistent /usr/bin/date
Segmentation fault (core dumped)
$ export LC_CTYPE=C
$ env - PATHOS=/nonexistent /usr/bin/date
Mon Oct 19 13:12:40 RDT 2009
$ export LC_CTYPE=fr_FR.ISO-8859-15
$ env - PATHOS=/nonexistent /usr/bin/date
Segmentation fault (core dumped)
$ export LC_CTYPE=dummy
$ env - PATHOS=/nonexistent /usr/bin/date
Mon Oct 19 13:12:41 RDT 2009
$ env - PATHOS=/nonexistent /usr/bin/env
PATHOS=/nonexistent
SYSTEMROOT=C:\WINNT
WINDIR=C:\WINNT
Hope this helps.
Regards.
