Re: [Gcl-devel] cvs build on linux aborts

Oops, my bad, no SEGFAULT is occuring.  I set a break on error, and
found the problem:

(gdb) run

After further digging, I noticed that getrlimit(RLIMIT_STACK) was
returning MAX_INT, so the stack size appears to be unlimited.  Perhaps
this is why this bug appears to be environment sensitive. For
testing purposes, I commented out this line in main

#ifdef RLIMIT_STACK
       getrlimit(RLIMIT_STACK, &rl);
       /* cssize = rl.rlim_cur/4 - 4*CSGETA; */
#endif 

and gcl works!  Now,  how to fix this properly?
