Hi!
src:perl currently fails to build from source on sh4 with:
./miniperl -Ilib make_ext.pl cpan/Archive-Tar/pm_to_blib MAKE="/usr/bin/make"
LIBPERL_A=libperl.a
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Unsuccessful Makefile.PL(cpan/Archive-Tar): code=11 at make_ext.pl line 518.
Makefile:586: recipe for target 'cpan/Archive-Tar/pm_to_blib' failed
make[1]: *** [cpan/Archive-Tar/pm_to_blib] Error 2
make[1]: Leaving directory '/<<PKGBUILDDIR>>'
debian/rules:124: recipe for target 'perl.static' failed
make: *** [perl.static] Error 2
dpkg-buildpackage: error: debian/rules build-arch gave error exit status 2
I have not tracked down the actual reason for the bug yet, but it can
be worked around by building perl without optimizations enabled on sh4.
The attached patch disables the optimizations on sh4 and makes the build
succeed. Please consider applying it for the next upload.
Thanks,
Adrian
