Apologies, I wasn't totally clear.  [prefix-]g++ and [prefix-]c++ are
aliased to the program but are found in the mingw32-gcc-g++.i686 package
listed above.  So you have it installed.

The above package is the C++ compiler.

On my VirtualBox installation of Fedora 14 I see:

$ yum list *gcc*
...

Good news.

This isn't uncommon if you don't explicitly set some important
configuration settings to sensible values e.g. Audio and TV playback
profile.  It shouldn't happen, so a gdb backtrace would be useful.

Is this on branch master?  Various recent changes have added to Windows
instabilities.  It would be nice to get these ironed out.  The
fixes/0.24 branch works OK on most Windows systems I have tried.

Thanks for your feedback.
