If one of a job's dependencies become unreacheable, this routine can
abort the job and clear the job pointer. Unfortunately, there was no
check at the end to see if this occured before doing some final job
processing at the end of the routine. This is now corrected in the
torque-1.1.0p5 snapshot. The corrected code is also listed below:
Thanks for bring this to our attention!
if (pjob != NULL)
pjob->ji_modified = 0;
if ((pjob != NULL) && (pjob->ji_modified != 0))
