1002,Building PGE dies with segfault when JIT enabled under Fedora 11,markmont,pmichaud,"Since JIT is deprecated, please disregard this ticket if it is a JIT issue; I'm only reporting it in case it is not.

When building parrot r41241 under Fedora 11 ""perl Configure.pl ; make"" results in:

{{{
[...previous output snipped...]
gmake[1]: Entering directory `/home/markmont/perl6/parrot/compilers/pge'
/usr/bin/perl -MExtUtils::Command -e rm_f PGE.pbc ../../runtime/parrot/library/PGE.pbc
/usr/bin/perl -e """" >PGE/builtins_gen.pir
../../parrot -o PGE.pbc --output-pbc PGE.pir
../../parrot ../../runtime/parrot/library/PGE/Perl6Grammar.pir  --output=PGE/builtins_gen.pir PGE/builtins.pg
gmake[1]: *** [PGE.pbc] Segmentation fault (core dumped)
gmake[1]: *** Deleting file `PGE.pbc'
gmake[1]: Leaving directory `/home/markmont/perl6/parrot/compilers/pge'
make: *** [compilers.dummy] Error 2
}}}

However, ""perl Configure.pl --jitcapable=0 ; make"" succeeds and the resulting built parrot works with rakudo.
