I'm not sure if this helps, but I get almost the exact opposite result, in 
that with 't' and 'c' under 5.8.8, the program hangs, and with with 5.11.0 
with 't' and 'c' the program runs through.  And with neither do I get an 'Out 
of memory!' message.

It may not be as simple as that (unless it's a regression >= 5.8.x ;)
Here's a resume of what happens to me (in several cases using the debugger 
(perl -d) on your test program:

	5.8.8 + c -> runs through.
	5.8.8 + t + c -> hangs.

	5.11.0 + c -> SEGV at line 65.
	5.11.0 + t + c -> runs through to line 119 (end of prog).

I've attached the -V and -Dr outputs from both 5.8.8 and 5.11.0, from both 
perls, and the output of several runs, for reference.
