Looking at that code, which is a tangle of goto statements and buffer allocations and accesses, it's a miracle any of it works in the first place. I bet there are tons more bugs in there.
Tangle of gotos? Those gotos all look reasonable -- they go to return conditions no longer than a few lines. Buffer allocations? They allocate to 2-3 buffers. That's all very reasonable. allocations and gotos aren't the devil in C.
