[petsc-users] valgrind

[Kuhlemann, Verena]

Hi,

I am trying to find an error in my program with valgrind.
The first message that I get is the following:

Syscall param write(buf) points to uninitialised byte(s)
==22395== Syscall param write(buf) points to uninitialised byte(s)

==22395==  Address 0x7feffef78 is on thread 1's stack

I am not sure what this is suppose to tell me. Is the something wrong with my PetscInitialize?

Thanks for the help,

Verena
