I got error message on terminal:
mmpbsa_py_energy: malloc.c:2451: sYSMALLOc: Assertion `(old_top ==
(((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof
(struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long)
(old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk,
fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) -
1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) ==
0)' failed.
