Hi,
turns out that there are a few more bad savestr calls even inside of pch.c.
Some of the code pathes are quite obvious that a NULL return value would
lead to a null pointer dereference, others would last longer before

program. If patch is in plan a mode, it will set an out_of_memory
flag, returns NULL and patch will try later on with plan b again.
