Reproducer

Description of problem:
When stepping through a function compiled with gcc 3.4.6-10 on gdb 6.3.0.0-1.159.el4, coming to the end of the function yields odd behavior: when you arrive at the closing curly brace and step, instead of jumping back to the parent function, you are shown the closing curly brace again. I attribute this to bad debug symbols because compiling the test case on RHEL 5 and then debugging it on the same version of gdb on RHEL 4 causes the problem to go away (I'm doing this by linking with -static since the RHEL 5 binary will be incompatible with the RHEL 4 glibc).

This has only been reproduced on ia64. x86_64 does not show this behavior.

Version-Release number of selected component (if applicable):
gcc 3.4.6-10
gdb 6.3.0.0-1.159.el4

How reproducible:
100%

Steps to Reproduce:
This problem can be reproduced by the attached "testpro.c".

1. Compile the reproducer:
  # gcc -g -o testpro testpro.c

2. Run gdb
  # gdb ./testpro

3. Set the Breakpoint
  (gdb) b sub_1

4. run

5. Executing the next or step sub command repeatedly
  (Please see the "Actual Results".)

Actual Results:
"}" is output two times.
