Comment(by heidnes):
I'm seeing a similar build problem on NetBSD/macppc 5.0_RC3, when the
porting fixes
from https://trac.parrot.org/parrot/ticket/512 have been applied.
Specifically, my
build dies at:
{{{
cc -o ./parrot src/main.o src/parrot_config.o
-L/usr/pkgsrc/lang/parrot/work/parrot-1.0.0/blib/lib -lparrot
-Wl,-R/usr/pkg/lib -lm -L/usr/pkg/lib -licuuc -licudata -lm -lm -lcrypt
-lintl -Wl,-R/usr/pkg/lib -pthread -Wl,-E
-Wl,-R/usr/pkg/lib/perl5/5.10.0/powerpc-netbsd-thread-multi/CORE
./parrot -o runtime/parrot/include/parrotlib.pbc
runtime/parrot/library/parrotlib.pir
Null PMC access in get_pmc_keyed_str()
*** Error code 1
}}}
The strange thing is that this builds cleanly on NetBSD/macppc 4.0.
The gcc versions are not terribly different: 4.1.2 with a few local fixes
on 4.0
and 4.1.3 on 5.0_RC3.
Testing with "perl t/harness --core-tests" results in
{{{
12 tests and 49 subtests skipped.
Failed 168/271 test scripts. 798/3156 subtests failed.
Files=271, Tests=3156, 352 wallclock secs (201.18 cusr + 80.74 csys =
281.92 CPU)
Failed 168/271 test programs. 798/3156 subtests failed.
}}}
on 5.0_RC3, but on 4.0 it gives a clean bill of health with
{{{
All tests successful, 10 tests and 577 subtests skipped.
Files=271, Tests=8638, 847 wallclock secs (347.51 cusr + 89.05 csys =

}}}
I have my parrot run under gdb, stopped in the function which prints the
above
message, but since I don't in general know my way around in the innards of
parrot,
I wonder "what next"?
