The following has be reported by IBM LTC:  
cscope SEGVs in ncurses in RHEL3 beta2 on x86_64
Hardware Environment:
x325 (Opteron)

Software Environment:
RHEL 3.0 beta2 for x86_64

Steps to Reproduce:
1. d/l cscope-15.5.tar.gz from cscope.sourceforge.net, unpack.
2. ./configure; make (build completes successfully)
3. ./src/csope

Actual Results:
Program received signal SIGSEGV, Segmentation fault.

Expected Results:
cscope-15.4 built and ran fine on SLES8 for x86_64 (built from
ftp://rpmfind.net/linux/SuSE-Linux/i386/8.2/suse/src/cscope-15.4-22.src.rpm)

Additional Information:
configure in cscope-15.4 doesn't x86_64 architecture:
checking build system type... Invalid configuration `x86_64-unknown-linux-gnu':
machine `x86_64-unknown' not recognized
configure: error: /bin/sh ./config.sub x86_64-unknown-linux-gnu failed.

SLES8 is no longer available on x86_64, so there's no way to check if
cscope-15.5 would have worked.  From the stack traceback it looks like the real
bug is in ncurses lib though, so cscope version may not be very relevant.

BTW, someone needs to add x86_64 (or AMD64, whatever's the official name now)
to bugzilla arch list.Glen/Greg - please submit this to Red Hat.  This is a
RHEL3 beta2 problem
on x86-64 (AMD64) platform (Opteron).  Thanks.
