[#CONC-495] Memory Leak found with LSan in ma

Hey our LSan run identified a memory leak in ma_net.c file. The memory allocated on line 311 is not freed when the function returns on line 340.

#ifdef HAVE_COMPRESS

  if (net->compress)

    free((char*) packet);

#endif

Direct leak of 102 byte(s) in 6 object(s) allocated from:

0 0x7f92a113ab78 in malloc /home/fcm/Perforce/SDK/UnixClang/dev/scripts/llvm_RELEASE_401_source/projects/compiler-rt/lib/asan/asan_malloc_linux.cc:66

Can I get a better context on how we could be running into this issue? Are there any known workarounds?
(we are avoiding making a custom version of the package)
