Subject: Re: [OMPI devel] VampirTrace and MPI_Init_thread()
From: Matthias Jurenz (matthias.jurenz_at_[hidden])

Hello Lisandro,

this problem will be fixed in the next Open MPI release. There was an obsolete
preprocessor condition around the MPI_Init_thread wrapper, so the source code
could never be compiled :-(

Thanks for the hint.

Matthias
