I bisected it, and unsurprisingly it's this commit​:

  Make lexicals visible inside of eval. This depends on some recent
Parrot changes, so bump up required version number. There are two parts
to this​: letting the parser know what lexicals are declared in the outer
scope so it doesn't claim about them being undeclared, and then doing a
.set_outer so the lexicals can be found at runtime.

eval() within a method fails with a "NULL PMC access" error,
though all tests + spectests pass ok.

This is on​:
rakudo version 44e1496989cf1b6f9fbd97152a31987841f2e0ff
parrot r37609

From @moritz

Tests are now (fudged) in t/spec/S29-context/eval.t.

Fixed in git 977b948, and we now have spectests for this too thanks to
moritz++, which I've unfudged.

Thanks,
