1.7.0-62: segfault when PATH is not set

[Denis Excoffier]

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.

Denis Excoffier.
