From @AlexDanielThis is actually a regression. The code makes sense (more or less), I can't see why would it error out like this. Bisectable points to (2017-01-31) rakudo/rakudo@9ed4449 On 2017-04-24 15:52:55, grondilu@yahoo.fr wrote:

If it worked before, then it was by luck. The extra sanity check added in MoarVM that produces this message prevented a mis-generated NFA from causing the VM to read junk memory. In some cases, that led to a SEGV. Anyway, the fix will be to figure out where in the NFA generator we are mis-generating things. That ain't the easiest thing to debug, but I will try and take a look at it soon, if I'm not beaten to it. The relevant code is in the NQP repository, under src/QRegex/NFA.nqp. /jnthn |
