Hi,
Programs compiled with -pg crash on exit if the variable PROFDIR is set. This
is a pretty old problem, a regression from egcs-1.1.1:
http://gcc.gnu.org/ml/gcc-patches/1999-03n/msg00038.html
The patch in the message doesn't work on SPARC64, so I've attached a slightly
modified version. Manually tested on
sparc64-sun-solaris2.9
sparc-sun-solaris2.8
sparc-sun-solaris2.7
sparc-sun-solaris2.6
sparc-sun-solaris2.5.1
Ok for 3.3 branch and mainline?
