[mpich-discuss] libcr error when using valgrind + mpirun

[Edgar Solomonik]

Hello,

After upgrading my system from Ubuntu 10.10 to 11.04 I am experiencing
difficulties running mpi with valgrind.  The upgrade seemed to have deleted
libcr-dev, which I reinstalled.

However, even after building clean versions of mpich2-1.3.1 and valgrind
3.6.1, I still get the following error, when running mpirun -np 4 valgrind
./app

cr_libinit.c:183 cri_init: sigaction() failed: Invalid argument

I am not sure if I have a bad libcr.   Or perhaps a later version of mpich2
is using check point restart as well as valgrind and cri_init is not
re-entrant.

Any help with this problem would be appreciated.  Including any different
approach for doing memory corruption/leak debugging when running an app with
mpich2-1.3.1.

Thanks,
Edgar
