libgcc @4.9.2_0: stage 1 configure fails with "cc1: internal compiler error: in init_reg_sets, at reginfo.c:178"

[Schamschula (Marius Schamschula)]

The update to libgcc 4.9.2, has broken the build under OS X 10.5.9. log is attached.

:info:build checking for suffix of object files... configure: error: in `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc49/libgcc/work/build/ppc-apple-darwin9/libgcc':
:info:build configure: error: cannot compute suffix of object files: cannot compile
:info:build See `config.log' for more details.

Well that’s weird. Can you upload config.log?

[larryv (Lawrence Velázquez)]

In the future, please comment after uploading files; our Trac doesn’t send email notifications for uploads.

That log does not exhibit any errors. Clean libgcc and try upgrading again, and attach the new main.log and config.log if it fails. (Make sure you upload the correct config.log; you probably want $(port work libgcc)/build/ppc-apple-darwin9/libgcc/config.log or something like that.)

Sorry, Larry, made a mental note about not adding a comment when attaching files.

To make sure I rebuilt after a port clean libgcc. Unfortunately with the same result.

I had forgotten that libgcc/gcc generate multiple config.log files, so I accidentally attached the top level file, which did not contain any useful info. I've replaced it with the file you suggested.

Same problem seen when building on a G4 PPC running 10.5.8.

Looks like a problem for upstream. To make sure, could someone try the build after disabling macosx-version-min.patch?

I just tried disabling the macosx-version-min.patch: I get the same error as before.

[larryv (Lawrence Velázquez)]

This is a known regression:

[Schamschula (Marius Schamschula)]

A patch has been made upstream. On my G5 iMac it successfully built both libgcc and gcc49 @4.9.2.

[larryv (Lawrence Velázquez)]

Do you see the issue with gcc48?

[Schamschula (Marius Schamschula)]

Larry,

Overnight my G5 rebuilt gcc48 to @4.8.3_2 without any problems.
