Description Sean Johnston 2003-09-04 14:01:44 UTC
Programs compiled with profiling (-pg) will crash on termination and not write 
any output profile data. This occurs when the environment variable PROFDIR is 
set.

This bug appears to have been spotted and a patch provided some time ago, 
however the patch does not appear to be present in the 3.3 source tree. Here is 
a URL for the original patch which also contains a better description of the 
issue than I can manage:

Comment 1 Sean Johnston 2003-09-18 11:08:37 UTC
The patch referenced in the original report has been tested and successfully 
resolves the issue.
Comment 2 Eric Botcazou 2003-09-18 11:49:51 UTC
Confirmed. Regression from egcs-1.1.1 according to Theodore.
Comment 3 Eric Botcazou 2003-09-18 11:51:00 UTC
Taking care of Theodore's patch.
Comment 4 Eric Botcazou 2003-09-18 12:19:27 UTC
The original patch doesn't work on SPARC64. The 'st' mnemonic should be replaced
by the macro 'stn'.
