Upgrade from LEPL 4.4.0 to 5.0.0 => out of memory

[Pedro Romano]

Hi! I've been using LEPL for my more complex needs for quite a while now and I love it! So, first of all, a big thank you to Andrew and other contributors, for the excellent and invaluable project that is LEPL.

My grammar has problem (probably some left-recursion issue somewere). With LEPL 4.4.0 the problem didn't manifest itself, however since LEPL 5.0.0 for some pathological input and grammar rule, the memory allocation just runs wild and soon the interpreter runs out of memory.

Is there any obvious thing I should be looking for that would be explained by the internal changes that happened between 4.4.0 and 5.0.0, that would help me to track down the culprit rule?

Thanks in advance for any help regarding this issue!

--Pedro.

I knew there were problems with memory, but not that this was new in 5.

Have you tried disabling memoisation? It could be that before 5 it was so
broken it didn't work. Use config.no_memoize().

Otherwise, an example of something (as simple as possible) that shows a big
difference between 4 and 5would help me track down the issue.
