Comment(by coke):
From a valgrind run against partcl (r440) on parrot (r39470) using
parrot tcl.pbc -e "puts hi"
The size of the context-related leaks are now greatly reduced, but still
present. Now including all the alloc_context related leaks instead of just
the biggest two.
Totals:
{{{
==12199== definitely lost: 30,925 bytes in 1,510 blocks.
==12199== indirectly lost: 4,316 bytes in 83 blocks.
}}}
Context related leaks:
