Maybe I've not had enough coffee, but isn't code in gettemp.c
missing a lot of tests? The trv pointer should never point
before path, but it can. Imagine path being "", then trv
will point at the NUL byte, and *(trv-1) will access the byte
before the passed argument.
I don't know if this is the cause of your problem, but it
sure looks buggy to me.
