Description Need Real Name 2002-10-15 18:02:47 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.0.1) Gecko/20020830

Description of problem:
Was having a number of segmentation faults in npasswd and kylix, decided to
compile latest glibc libraries on suspicion glibc was culprit.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.untar glibc-2.3.1
2.configure with linuxthreads and /usr/local/gnu for path
3.make 
	

Actual Results:  In file included from ../sysdeps/ieee754/ldbl-96/strtold.c:43:
strtod.c: In function `__strtold_internal':
strtod.c:1566: internal error: Illegal instruction
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions.
make[1]: *** [strtold.o] Error 1
make[1]: Leaving directory `/linuxdat/tarballs/glibc-2.3.1/stdlib'
make: *** [stdlib/subdir_lib] Error 2
[root@linux glibc-2.3.1]#
[root@linux glibc-2.3.1]# find ./ -name strtod.c
./stdlib/strtod.c
[root@linux glibc-2.3.1]# cd ./stdlib/
[root@linux stdlib]# emacs strtod.c


Expected Results:  That I could build the package

Additional info:

Assume this is really a GNU problem but RedHat request for "bugzilla"
popped up. Si here it is. The real problem is "segfaults" will check Kylix site
for ideas.
Comment 1 Jakub Jelinek 2002-10-15 18:12:51 UTC 
Is it reproduceable, always on the same file same error?
I'm building glibc very often and have not seen anything like this.

Second attempt to reproduce.. further along in make but same error
Comment 3 Jakub Jelinek 2002-10-16 14:00:38 UTC 
If it doesn't die on the same file all the time, it is most probably flaky
hardware. Check with memtest86 your memory etc.
Nothing to do with gcc.
gcc bug would be reproduceable always on the same file.
