[petsc-users] PETSc/petsc4py error detection

[Nicola Creati]

Hello,
I'm writing a large application in Python that uses petsc4py to solve 
some equations. Running my code I note that PETSc detects errors in 
sections (I believe in Cython extensions and packages) where petsc4py is 
not imported or used. I do not need to fix the problem, I already did 
it. Is there a way to avoid petsc4py/PETSc to catch errors in not PETSc 
sections of the code?
This is an example of the error message I got:

[0]PETSC ERROR: 
------------------------------------------------------------------------
[0]PETSC ERROR: Caught signal number 11 SEGV: Segmentation Violation, 
probably memory access out of range
[0]PETSC ERROR: Try option -start_in_debugger or -on_error_attach_debugger
[0]PETSC ERROR: or see 
http://www.mcs.anl.gov/petsc/documentation/faq.html#valgrind[0]PETSC 
ERROR: or try http://valgrind.org on GNU/linux and Apple Mac OS X to 
find memory corruption errors
[0]PETSC ERROR: likely location of problem given in stack below
[0]PETSC ERROR: ---------------------  Stack Frames 
------------------------------------
[0]PETSC ERROR: Note: The EXACT line numbers in the stack are not available,
[0]PETSC ERROR:       INSTEAD the line number of the start of the function
[0]PETSC ERROR:       is given.
--------------------------------------------------------------------------
mpiexec noticed that process rank 0 with PID 25694 on node daisy exited 
on signal 11 (Segmentation fault).
--------------------------------------------------------------------------

I'm using Python 2.7.6, petsc4py 3.4 and PETSc 3.4.3.

Thanks.

Nicola
