gcc-4.1.0-17
glibc-2.4.90-7


How reproducible:

Steps to Reproduce:
1. compile a hello world with -g
2. gdb a.out
3. run
  
Actual results:
Segmentation fault



Expected results:

Comment 1 Doug Chapman 2006-05-16 15:49:45 UTC

A little more info...

I also tried compiling with -static with the same results.  Also tried compiling
both normal and static on a RHEL4 system and running on rawhide with the same
results.

Comment 2 Tony Luck 2006-05-16 16:08:29 UTC

Works (sort of) (on a slightly older?) RHEL4 installation.

$ gdb --version
GNU gdb Red Hat Linux (6.3.0.0-0.31rh)

$ rpm -q -f /usr/bin/gdb
gdb-6.3.0.0-0.31

I do see a "Failed to read a valid object file image from memory." on startup 
of gdb, and when I type "run", but no SIGSEGV, and things otherwise seem to be 
working (can set breakpoints, gdb stops at them and prints reasonable location 
information).  This was with a kernel.org kernel.  Running with RHEL4 kernel 
2.6.9-34.EL, I see similar results ... gdb works, but there are some warning 
messages (e.g. "warning: cannot close "shared object read from target memory": 
File in wrong format").

Comment 3 Doug Chapman 2006-05-16 17:21:24 UTC

Tony's note above gave me the idea to try the RHEL4 gdb on rawhide.  I removed
gdb and installed gdb-6.3.0.0-1.96.ia64.rpm from the RHEL4 tree.  This version
of gdb works with no problem.  I don't see the error that Tony mentions here.

Comment 4 Doug Chapman 2006-05-16 18:23:08 UTC

Created attachment 129253 [details]
stack trace of gdb segvault

This was created by setting "ulimit -c" so that gdb would create a core file
then using the RHEL4 gdb to read that core and get a stack trace.

Comment 5 Émeric Maschino 2006-05-16 19:04:29 UTC

FYI, gdb-6.3.0.0-1.122 shipped with the ia64 FC5 ISO DVD image posted by Prarit
on oss.sgi.com is running fine too.

Comment 7 Alexandre Oliva 2006-05-17 13:54:38 UTC

Thanks for the report, this should be fixed in tomorrow's rawhide,
gdb-6.3.0.0-1.129.FC6.ia64.

Comment 8 Émeric Maschino 2006-05-18 23:49:51 UTC

I confirm that today's Rawhide gdb-6.3.0.0-1.129.FC6 is working again. Many
thanks for this quick fix.

Comment 9 Fedora Update System 2006-09-15 01:46:46 UTC

gdb-6.3.0.0-1.134.fc5 has been pushed for fc5, which should resolve this issue.  If these problems are still present in this version, then please make note of it in this bug report.
