An error in memory allocation elsewhere could cause problems.  What's
the smallest *compilable* code segment you can post which exhibits this
behavior?  Nothing jumps out at me as wrong, here.

To be pedantic, I'd suggest you declare names as const char *, but that
is almost certainly not relevant to your problem.
