>Description:
In NetBSD/sh3-port (landisk, hpcsh, ...) 7.0_BETA, some binaries does not work correctly.

1) For building pkgsrc, the gcc occurs SIGSEGV.
 see http://mail-index.netbsd.org/port-sh3/2014/08/16/msg000112.html

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. 

and, 
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:
 http://www.yagoto-urayama.jp/~oshimaya/netbsd/files/atf/netbsd-7/landisk/20141002/
 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.

>How-To-Repeat:
1) install NetBSD 7.0_BETA to NetBSD/sh3 port
2) build pkgsrc/pkgtools/digest
or 
2') run atf-run in /usr/tests/fs/psshfs



>Fix:
no idea.
