GDC compiler crash -- latest GitHub source built against gcc-snapshot-20130209

[Joseph Rushton Wakeling]

Hello all,

I built the latest from-GitHub source against an up-to-date gcc snapshot 
(20130209, the latest in Ubuntu 13.04).  The build completes successfully and 
was installed, but when running it crashes with the following error:

Any thoughts on what's wrong?  This was built using the following configure:

../gcc-snapshot-20130209/src/configure --enable-languages=d --disable-multilib 
--enable-checking=release --prefix=/opt/gdc

I'm guessing that probably the gcc-snapshot is too recent?
