exceptions and -fomit-frame-pointer

[Bill Woessner]

I just started experimenting with C++ exceptions.  I've also long used
-fomit-frame-pointer in compiling all my code.  But today, when adding
exceptions to my C++ matrix package, I discovered that they didn't work.
The exception was thrown but not caught (resulting, of course, in a
segmentation fault).  I traced the reason they didn't work to compiling
with -fomit-frame-pointer.  I don't know if this is supposed to happen,
but I thought I'd at least bring it to your attention.  Removing
-fomit-frame-pointer from CFLAGS in my makefile fixed the problem.  For
reference, I use a PII-233 with 32MB of RAM running Linux 2.0.36, egcs
1.1b, and glibc 2.0.6.  Please feel free to ask for any other information
I can provide you.
