Broken frame JIT compiled
Raw
Comments.txt
I'm reasonably fairly sure that the JIT compilation of this frame - and no other - is necessary for our continued failure.
Why is this so?
a): this is the exact frame that's JIT compiled just before our regexes start misbehaving in nqp/t/qregex/01-qregex.nqp
(which is just before test 56 if you just use the 'subrules' file)
b): disable JIT compiling it (by inserting a known-uncompilable frame?)
c): it's not related to OSR (even though it adds OSR points, because MVM_spesh_osr_finalize is not called in this case, and it really just starts at the beginning)
