| Comment | There haven't been any real problems with strict aliasing for quite some time, so it should be safe to enable by now. |
Description
If compiled with gcc-4.4 and '-O3 -Wstrict-aliasing' the grid checks test-ug and test-alu2dsimplex complain about violations of the strict aliasing rule.
Referring to http://gcc.gnu.org/gcc-4.4/porting_to.html gcc-4.4 seems to more strict.
