Folks, I've just built 1.8.5 to test with mpi4py. My configure line was: $ ./configure --prefix=/home/devel/mpi/openmpi/1.8.5 --enable-debug --enable-mem-debug
While running the tests, my terminal was flooded with malloc(0) warnings, below a list of unique lines. malloc debug: Request for 0 bytes (coll_libnbc_ireduce_scatter_block.c, 67) malloc debug: Request for 0 bytes (nbc_internal.h, 505) malloc debug: Request for 0 bytes (osc_rdma_active_target.c, 74) malloc debug: Request for 0 bytes (osc_rdma_active_target.c, 76) -- Lisandro Dalcin ============ Research Scientist Computer, Electrical and Mathematical Sciences & Engineering (CEMSE) Numerical Porous Media Center (NumPor) King Abdullah University of Science and Technology (KAUST) http://numpor.kaust.edu.sa/ 4700 King Abdullah University of Science and Technology al-Khawarizmi Bldg (Bldg 1), Office # 4332 Thuwal 23955-6900, Kingdom of Saudi Arabia http://www.kaust.edu.sa Office Phone: +966 12 808-0459
