I am getting a seg fault when doing a very simple subroutine call with IMCC:
.sub _main newsub $P4, .Sub, _two_of $P6 = new PerlHash .pcc_begin prototyped .arg $P6 .arg 14 .pcc_call $P4 after: .pcc_end end .end .pcc_sub _two_of non_prototyped .param PerlHash Sunknown_named3 .param int mode .pcc_begin_return .pcc_end_return .end The problem is that IMCC is checking to see whether the 1st argument is of the correct type (PerlHash), but it looks for the argument in P3[0], when in fact it isn't an overflow arg and so is in P5. P3, in fact, is null and so parrot seg faults. Oddly, if I take away the int parameter (and corresponding argument), it does not crash. But this also seems to remove the typecheck entirely.
