>Description:
During a long build (cygwin32 as cross compiler) /bin/sh
called from gmake dumps core inside popstackmark().
Replacing the 2.1-stable sh with a 2.2.5-RELEASE one didn't
help, so i tried the patch below: now its still building
as i write this.
>How-To-Repeat:
I can send my (unfinished) port if your intrested, but you'll
need some 250 MBytes free and wait a while before it gets
to the point where it happenes. this is the C file i used
to attach gdb to the offending sh command:
