Hi, We are compiling with mpich/master each night since august 2016... since nov 8, the mpich/master branch is buggy with our nighlty build tests. Here is the nov 8 config.log: http://www.giref.ulaval.ca/~cmpgiref/dernier_mpich/2017.11.08.05h36m02s_conf... For nov 7 the configure log: http://www.giref.ulaval.ca/~cmpgiref/dernier_mpich/2017.11.07.05h36m01s_conf... Since nov 8, on a specific ROMIO test, it is hanging indefinitely in optimized mode, and into DEBUG mode, I have a strange (yet to be debugged) assertion in our code. I reran the test manually, and when I wrote the results on a local disk, everything is fine. However, when I write over *NFS*, the test is faulty. I have not yet debugged enough through this, but, I suspect something related with one of: MPI_File_write_all_begin MPI_File_write_all_end MPI_File_read_all_begin MPI_File_read_all_end MPI_File_set_view MPI_Type_free Am I alone to see these problems?
