Memory leak on sub call

[quietfanatic]

This affects at least revision 42403.

The following loop shows a large memory leak when a sub is invoked. This leak makes running certain realtime applications impossible.

.sub 'main'

lab:

'foo'() goto lab

.end .sub 'foo' .end

Since newlines were lost in the formatting I have attached the program as a file

I can't confirm this with Valgrind and Parrot's --leak-test flag, so we do 
release the memory on process exit, but it's clear that something continues to 
allocate more memory if I watch the process in top.  I'll continue to 
investigate.

I believe I've fixed this in commits r42427, r42428, r42430, and r42431. Thanks for the report.
