[petsc-users] Optimized run crashes on one machine but not another

[Garnet Vaz]

Hi,

I just rebuilt PETSc on both my laptop and my desktop.
On both machines the output of >grep GIT configure.log
        Defined "VERSION_GIT" to
""d8f7425765acda418e23a679c25fd616d9da8153""
        Defined "VERSION_DATE_GIT" to ""2013-08-27 10:05:35 -0500""

My code runs on both machines in the debug build without causing
any problems. When I try to run the optimized build, the code crashes
with a SEGV fault on my laptop but not on the desktop. I have built
PETSc using the same configure options.

I have attached the outputs of valgrind for both my laptop/desktop for
both the debug/opt builds. How can I figure out what differences are
causing the errors in one case and not the other?


Thanks.
