mprotect(0x7f5fd97df000, 4096, PROT_NONE) = -1 ENOMEM (Cannot allocate

Have you checked available memory on your system ? Or user limit ?
You test program is going to allocate
79 + 1 pages for bm
1 + 1 for each double arrays (x 40000)
So in the end your program is allocating 80080 pages, so about
312MBytes.
It not that big for a 64bits system.
afaics in gdb, the mprotect fails at i=32756. it's near to 2^15.
maybe some kernel data structures are full?
