Fwd: mysql-cluster-7.2.6 build failed GCC-4.7

[Mauritz Sundell]

Hi nanashi,
yes it looks related to gcc-4.7.

I have a patch below that should fix at least the compilation
error in HashMap2.cpp.  But since I not for the moment have
access to a build environment with gcc-4.7 where could be more
errors related to gcc-4.7.

I'm using Slackware-current GCC-4.7 cmake-2.8.8 linux kernel 3.2.14

Although mysql-5.5.24 server built successfully, I'm trying to build
mysql-cluster-gpl-7.2.6 and I'm getting a build failed with

It must be gcc-4.7 related, according to
http://gcc.gnu.org/gcc-4.7/porting_to.html
