Hi PETSc users/developers,

I am having some difficulties with the -log_history option on example 
PETSc codes at my local installation (FYI: Cray XT architecture). When 
executing the ex2.c code (for example) on multiple processors with the 
-log_history option I keep getting:

Signal number 11 SEGV: Segmentation Violation, probably memory access 
out of range

The log history file is created though but contains the following:

Without the -log_history option the code runs as expected.

Is this a build/architecture issue at my end?

Thanks in advance for any advice given.
