 Most of the problems detected by jemalloc were double frees.
 It was idenitifiable by it segfaulting while dereferencing something,
 and the object having the address 0x5a5a5a...
 
 Another option that is very good at detecting these bugs is compiling
 the test programs with -fsanitize=address and turning off ASLR.
