Subject:
weird perl6/plumhead problem
mod_parrot can load multiple HLL compilers in the same interpreter, and on
my server i'm using both perl6 and plumhead. this works fine if i load
perl6 before plumhead. however, if i load perl6 *after* plumhead, i get a
nasty error:
push_pmc() not implemented in class 'Sub'
i get the same error with this plain PIR:
.sub main :main
print "loading plumhead\n"
load_bytecode "languages/plumhead/plumhead.pbc"
print "loading perl6\n"
load_bytecode "languages/perl6/perl6.pbc"
print "done\n"
.end
jeff@groovy:~/build/parrot$ ./parrot foo.pir
loading plumhead
loading perl6
push_pmc() not implemented in class 'Sub'
current instr.: 'main' pc 6 (foo.pir:5)
any ideas? backtrace is below.
