5.8.8 certainly cures the problem with my cut down code above, but not with the code from which it is derived :(

Now to go through the process of reducing it all over again.

Update:

If you get a moment, could you try wrapping the sub call in the OP code in a loop and calling say 10 times under 5.8.8? From what I am seeing, it appears that 5.8.8 allows me to call it twice without failure, but goes belly up after 4 or 5 times.

The cuprit appears to be something in GD, but a quick scan of GD.xs shows none of the bad things demo'd in in the OO Inline C example. It use Safemalloc/Safefree exclusively and make no calls to str(n)dup(), or any of the other dodgey crt string functions.

I tried upgrading GD to 2.30. It builds clean(ish), but segfaults when running it's testsuite. (And yes. I made sure I had the latest version of gdlib: v2.0.33 :)
