So some non-terminating recursive call it seems.
(if my debugging has any value at all.)

i compiled it successfully by:

gcc -m32 -O -c ~/Downloads/source.i -o ~/source1

gcc -v:

Using built-in specs.

Your compiler is too old to show the problem.
gcc 4.6.2 is required.

AFAIK this bug has been fixed in gcc trunk and 4.6 branch,
more info at the bug# referenced from here.

I too get this error while compiling Mahogany. Applying gcc47-pr51077.patch helps.

gcc-4.6.3-2.fc16,libtool-2.4-9.fc16,gcc-python-plugin-0.9-1.fc16 has been submitted as an update for Fedora 16.
https://admin.fedoraproject.org/updates/gcc-4.6.3-2.fc16,libtool-2.4-9.fc16,gcc-python-plugin-0.9-1.fc16

Package gcc-4.6.3-2.fc16, libtool-2.4-9.fc16, gcc-python-plugin-0.9-1.fc16:
