The address sanitizer report a direct memory leak in the get_supported_protocols function:

#0 0x7f143be737ae in calloc (/lib64/libasan.so.5+0x10c7ae)
#1 0x600cb1 in get_supported_protocols /home/centos/storm-frontend.git/src/frontend/storm_util.c:63

At that line there is the allocation of a 10-character string in a loop:

sup_protocols[i] = calloc(protlen, sizeof(char));

The overall array of protocol strings is freed in the caller of that function, without first looping and freeing the 10-char arrays.

It's not clear if the allocated size vs the actual size of the protocols array is available in the caller.
