[BUG] OP_POP_REPL can cause a segfault

[Jason2605]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

OP_POP_REPL pops the value off the stack and then attempts to print it if it's a non-nil value. OP_POP_REPL also has a call to tableSet, this can trigger a GC if the table needs to resize. Since the value has been popped off the stack, there is potential that it's not being tracked by the GC so when we attempt to print the value it's attempting to print something thats been free'd causing a segfault to occur.

Expected Behavior

No segfault.

Steps To Reproduce

This was found when testing the following PR with Dictu built in debug: #445

In the repl enter the following

>>> import Path;
>>> Path.join(['/tmp', '/////abcd/////', '/efg/']);
/tmp/abcd/efg/
>>> Path.join(['/tmp', '/////abcd/////', '/efg']);

Anything else?
