Using the more elaborate version of the testcase behind #58294, which has a two and a three argument version of max, what use to compile and execute incorrectly before the bug fix now compiles and segfaults. I suspect this has nothing to do with the changes that fixed #58294, and everything to do with recent MMD changes. But that's speculation I've stripped it down to the max(a,b) and max(a,b,c) definitions and one three-arg call, though a two-arg call produces a similar result. The result is: sully:perl6 stephensimmons$ perl6 experiment/max3.p6 Null PMC access in invoke() current instr.: '_block11' pc 44 (EVAL_14:19) called from Sub 'parrot;PCT::HLLCompiler;eval' pc 806 (src/PCT/HLLCompiler.pir:481) called from Sub 'parrot;PCT::HLLCompiler;evalfiles' pc 1078 (src/PCT/HLLCompiler.pir:610) called from Sub 'parrot;PCT::HLLCompiler;command_line' pc 1257 (src/PCT/HLLCompiler.pir:699) called from Sub 'parrot;Perl6::Compiler;main' pc 16414 (perl6.pir:172) perl6(22765) malloc: *** error for object 0x343ea10: double free *** set a breakpoint in malloc_error_break to debug Segmentation fault sysinfo: sully:perl6 stephensimmons$ perl6 -v This is Rakudo Perl 6, revision 31194 built on parrot 0.7.0-devel for darwin-thread-multi-2level.
