This is the correct patch (same as previous minus the debugging
statements).

The problem was found and fixed. Until the patch get applied to the
1.1 and 1.2 branches please use the attached patch.
System: BLACS 1.1p3 on Debian Linux 3.1r3 on dual-opteron, gcc 3.3.5,
Intel ifort 9.0.32 all tests with 4 processors (comments below)
OpenMPi 1.1.1 patched and OpenMPI 1.1.2 patched:
C & F tests: no errors with default data set. F test slowed down
in the middle of the tests.
OpenMPI 1.3a1r11962 patched: much better, completes all tests with
default data set but the tester crashes on exit (different problem?)

The final auxiliary test is for BLACS_ABORT.
Immediately after this message, all processes should be killed.
If processes survive the call, your BLACS_ABORT is incorrect.
{0,2}, pnum=2, Contxt=0, killed other procs, exiting with error #-1.

Results of testing the patch on my system:
1) Not certain which branches this patch can be applied to so I may
have tried to do too much.
2) I don't have 11970 on my system so I tried to apply the patch to
1.1.1, 1.1.2rc1, 1.3a1r11962
(no nightly tarball for 1.3a1r11970 this morning)
(side note where is 1.2?, only via cvs?)
3) patch complained about all three I tried to apply it to but seemed
to apply the patch most of the time, I hand-checked all three patched
routines in the three branches I tried and hand fixed anything that
got missed because of differences in line numbers.
4) The patch applied best against 1.3a1r11962 and second best against
1.1.1 -- my lack of experience with patch likely confused the issue.
