From perl6@6dof.xyz* How to reproduce (where ip is the attached file): perl6 -e "say 'ip'.IO.lines.hyper.map(* ~~ /:constant @l = (1 ... 255).list; @l ** 4 % '.'/).all.so" * Expected output: True that is, as without .hyper: perl6 -e "say 'ip'.IO.lines.map(* ~~ /:constant @l = (1 ... 255).list; @l ** 4 % '.'/).all.so" * Current output (any of the 5 following ones): False Segmentation fault (core dumped) Internal error: invalid thread ID 471 in GC work pass Can only resume an exception object *** Error in `/home/user/.rakudobrew/glr-nom/install/bin/moar': double free or corruption (!prev): 0x00007ff45c1c70b0 *** |

I did some tests, and sadly it still segfaults: $ perl6 -e "say 'ip'.IO.lines.hyper.map(* ~~ /<{ (1...255).list }> '.'/).list" and: $ perl6 -e "say 'ip'.IO.lines.hyper.map(* ~~ /<{ (1...255).list }> '.'/).list" where: $ perl6 --version |

It seems that we do an EVAL when interpolating the regex, and that some issues with thread safety in the Perl 6 compiler (or perhaps in the way it gets code-gen'd) is at least somewhat to blame. This crashes in similar ways: perl6-m -e "await (^1000).map({ start { EVAL '/0|1|2/' } }); say 'ok'" Turning on MVM_CROSS_THREAD_WRITE_LOG shows various suspect things. |
