The input buffer varies. The pattern is a 1300 word long list of
\b(word1|word2|etc)\b
The error valgrind gives is:

==10046== Conditional jump or move depends on uninitialised value(s)
==10046==    at 0x41EC11D: ???
==10046==    by 0x3ED: ???
==10046==    by 0x41AF09A: ???
==10046==  Uninitialised value was created by a stack allocation
==10046==    at 0x40FC71: myfunc (myfile.c:64)



Those stack frames are nonsense, but the allocation frame is real. I'll try
mallocing the region instead of using the stack.
