NetBSD usl5p2 7.0_BETA NetBSD 7.0_BETA (GENERIC.201410031710Z) landisk
In NetBSD/sh3-port (landisk, hpcsh, ...) 7.0_BETA, some binaries does not work correctly.
1) For building pkgsrc, the gcc occurs SIGSEGV.
2) When atf-run in /usr/tests/fs/psshfs, it fails.
the mount_psshfs got signal 4(SIGILL). it is very strange.(*1)
For comparison, I build NetBSD/landisk binary with GCC45 by build.sh -V HAVE_GCC45 and run,
1) 'make pkgsrc/pkgtools/digest' success.
2) atf-run psshfs passed, SIGILL does not occur.
2') in GCC4.8 (Normal release binary) environment,
I copy libpuffs.so.2 binary built by GCC4.5,
atf-run psshfs passed, successful.
In this case, the problem is in libpuffs.so.2 built by gcc4.8 only.
I think these problems are caused by GCC48 for netbsd/sh3, it may generate worse binary.
(Now GCC48 is the default for NetBSD/sh3 in netbsd-7 and current)
*1: results of all atf-run in /usr/tests is here:
gcc48/ is by the normal release binaries in NetBSD7.0_BETA,
gcc45/ is by binarries built with -V HAVE_GCC=45 in netbsd-7 tree.
1) install NetBSD 7.0_BETA to NetBSD/sh3 port
2) build pkgsrc/pkgtools/digest
2') run atf-run in /usr/tests/fs/psshfs
