-fstack-check

Is it expected that -fstack-check works correctly?  I've tried both
gcc 2.95.2 and the current CVS gcc.  Setup is Linux kernel 2.2.16
on i686, binutils 2.10, glibc 2.1.3.

I'm compiling code that I *think* is OK with -fstack-check and I get
segfaults.  Do the libraries I link with also need to be compiled with
-fstack-check?

I'm just not finding a lot of information on this flag and its
intended usage, I'd appreciate any info anyone can supply.

Thanks!

	Charles G Waldman
