Description Caspar Zhang 2010-06-08 07:13:25 UTC

Description of problem:

When I tried to load trace.so module in crash by using `extend /path/to/trace.so', it returns error:

extend: /usr/lib64/crash/extensions/trace.so: no commands registered: shared object unloaded

in older version (1.2.el6) this command works, I regard it as a regression.

Version-Release number of selected component (if applicable):
crash-5.0.0-14.el6
crash-trace-command-1.0-1.2.el6

How reproducible:
100%

Steps to Reproduce:
1. install crash-trace-command and run crash
2. run extend /path/to/trace.so
  
Actual results:
error occur: extend: /usr/lib64/crash/extensions/trace.so: no commands registered: shared object unloaded

Expected results:
module loaded: /usr/lib64/crash/extensions/trace.so: shared object loaded
