libgcc-devel @4.9-20131215: internal compiler error: Illegal instruction

[stavros.vagionitis@…]

When I try the sudo port -v upgrade outdated I get the following error

Any clues? The current version of gcc is 4.2. I have a MacOSX 10.6.8 64 bit. Following the output of uname -a

Darwin stavrosmac-6.lan 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun  7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386 i386 MacBookPro5,5 Darwin

For the same port, compiling in 10.9.1, I get the error that the function darwin_function_section( ) in file /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc49/libgcc-devel/work/gcc-4.9-20131222/gcc/config/darwin.c erroneously reaches the end of the function without a return statement, even though it is supposed to return a value.

Now relevant for Yosemite:

Is this still relevant with gcc-devel now at 12-20210801? I'll take me some effort to get MacOS 10.6 running for testing / debugging.

Latest version builds fine in buildbots.
