I'm sorry but this test case is way too complicated to debug.
The only advice I can give is that it is unlikely that there is a problem
with realloc. SIGSEGVs are usually an indication of some sort of memory
corruption like overrunning a 20 byte array with 24 bytes of info.
realloc SIGSEGVs can come about as a result of attempts to realloc a block
that was not malloced or at least not malloced using a malloc that is
associated with realloc.
If you can pare this down into twenty lines or so, then maybe someone would
be willing to take a look at it. I don't think that anyone has the time
to attempt to debug a program of this size, however.
