Preprocessed source that triggered the internal compiler error
Reported upstream: http://www.iro.umontreal.ca/~gambit/bugzilla/show_bug.cgi?id=155 This bug is fixed in GCC 4.7.0 (as tested on the PPC test machine's fedora-rawhide-ppc64 target) but present as late as GCC 4.6.2 (tested on the fedora-16-ppc64 target) as well as the GCC 4.4.6 release shipping with EPEL 6. Compiling with -O1 (which is the default up to Gambit 4.6.3) works around this problem, but upstream points out that it's a GCC problem. Upstream bug report: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52829 Since RHEL 6.3 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker.

This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development. This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4. This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux.
