Description phil 1999-07-09 21:55:50 UTC

I have an executable that causes /usr/bin/gprof on Redhat
6.0 Alpha to give a segmentation fault and dump core, as in
  /usr/bin/gprof ep.S.1.gprof

The ep.S.1.gprof and gmon.out files are available in
 ftp://ftp.cs.arizona.edu/pub/phil.

I have mail from Ian Taylor (ian) which says
Jeff Law has checked in a patch to egcs which appears
to fix the problem:
 Tue Jun 29 01:37:53 1999 Jeffery A Law  (law)

 * expr.c (emit_block_move): Properly handle case where one
 of the block move arguments has a queued increment or
 decrement.
 (clear_storage): Similarly.  Fix formatting goof.

Let me know if i can provide additional information.

Thanks.

the graphic profiler gprof which is part of the binutils
suite shipped with red hat 6.0 - alpha
(binutils-2.9.1.0.23-4) seg faults dumping core.

it seems to me that this bug is unrelated to bug 3970.

Comment 2 Jim Kingdon 1999-07-24 17:02:59 UTC

I don't see any files at ftp://ftp.cs.arizona.edu/pub/phil
I'd like to see source code as well as the profiling data.

Comment 3 Jim Kingdon 1999-07-30 21:23:59 UTC

I have verified Ian's diagnosis and have uploaded egcs-1.1.2-17
which has the fix which Ian suggests.

where did you upload egcs-1.1.2-17 to? i cannot find it on the rufus
database since i want to fix the problem on my machine as well.

thanks, helmut.

Comment 4 Jim Kingdon 1999-08-30 02:26:59 UTC

Helmut:
egcs-1.1.2-19 is part of rawhide (see http://developer.redhat.com/
for general information or http://www.redhat.com/download/mirror.html
for a list of mirror sites - see the rawhide directory).

Comment 5 helmut katzgraber 1999-08-30 16:55:59 UTC

egcs-1.1.2-19 still seg faults with my code when i invoke gprof on the
alpha.

Comment 6 Jim Kingdon 1999-08-30 17:44:59 UTC

You need to recompile gprof (or get binutils-2.9.1.0.23-5).
Also bug #4395.

Comment 7 helmut katzgraber 1999-08-30 23:02:59 UTC

cannot find the binutils-2.9.1.0.23-5 on rawhide. only ...23-4. when
can i expect it to be posted there? h.

Comment 8 Jim Kingdon 1999-08-31 14:54:59 UTC

Rawhide releases happen once a week and binutils-2.9.1.0.23-5
should be in the next one.
