For my program right now I'm using a souped-up version using a

Hmm I was wondering if I needed it to be static, and verily,
substituting:
char[] name = "/tmp/XXXXXX".dup;
instead gives a proper output *some* of the time but mostly gives
the error:

Is it because the D slice is subject to relocation and C is
occasionally not able to access the proper pointer?
