Reproducible: Always
Steps to Reproduce:
Tested on libtool 1.3.5, pdksh 5.2.14:
1. cp /usr/bin/libtool ~/
2. vi ~/libtool and change s#!/bin/ksh
3. run libtool throught this (gdb) simple script (not directly):
mkdir -p /tmp/testXYZ && cd /tmp/testXYZ
~/libtool --mode=link gcc  -O2 -march=i686 -Wall -Wunused  -s -o

Comment 1 Trond Eivind Glomsrxd 2001-03-12 10:34:48 EST
Can you try getting the new kernel, pdksh and glibc from wolverine (or even
better: Rawhide) and try it again?

Also, how do you run that through gdb? I tried runninng the looong command line
in pdksh (after switching to ksh in ~/libtool), and couldn't reproduce your crash:

gcc: gtkdial.lo: No such file or directory
gcc: gtkpixmapmenuitem.lo: No such file or directory
Comment 2 Arkadiusz Miskiewicz 2001-03-12 14:20:16 EST
Please ignore this bug report. I also have gcc 2.95.3-test4 (not from RH) and it
seems that it miscompiles pdksh. pdksh compiled using officiall compilator
from RH (I also tested this with gcc 20010305 snapshot) works fine.
