Bug#637236: gcc-4.6: FTBFS on kfreebsd-amd64: gengtype: Internal error: abort in get_output_file_with_visibility, at gengtype.c:1998

thanks

It appears that gcc-4.6 4.6.1-13 built successfully on the buildd, 
fano.d.o. Downgrading this bug so gcc-4.6 can migrate to testing.

However the buildd logs contain a disturbing history of failures, 
retries and eventual successes:

4.6.1-13 OK on fano
         FTBFS on fasch
         FTBFS on fasch
         FTBFS on fano

4.6.1-12 OK on fano

4.6.1-11 OK on fasch
         FTBFS on fasch
         FTBFS on fano

4.6.1-10 OK on fasch
         FTBFS on fasch

4.6.1-9  OK on fasch
         FTBFS on fasch
         FTBFS on fasch
         FTBFS on fano

etc.

I would very much like to understand the changes on both buildd 
machines that allow the package to build, or cause it to FTBFS.
