This might be related to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48891 . The options list used was the simfactory ubuntu.cfg one.

Comment (by eschnett):
A slightly unrelated question: Why are you using a 32 bit machine? A 64 bit machine would presumably be faster.

Comment (by rhaas):
I believe I had trouble getting the 64bit version to install in VirtualBox. This was on my laptop which lacks full hardware (ie. eg HVM does not work) virtualization. It would crash right at the installation menu I think. This might work on my workstation where I have a somewhat more featureful CPU.

Comment (by sbrandt):
My compiler is gnu 4.7.2 on Fedora 17 and it shows the problem. The idiom {{{ using namespace std; isnan(x); }}}
is not handled correctly on my platform. Alas.
However, this error seems tied to the use of -std=c++0x. If I compile with -std=c++03 everything appears to be fine. Maybe the fix is to remove std=c++0x from simfactory settings?

I treat this as a duplicate of #1121, which now has a patch for review.
