some time ago I reported problems using
ublas with gcc-3.0.
I've just realized that using gcc-3.0.3
my problems disapeared.

Concerning performance I made the following

Using the optimization flags
-march=i686 -O3 -fomit-frame-pointer -funroll-loops
gcc-2.95.4 produces codes which is 5% faster than
gcc-3.0.3, but gcc-3.0.3 allows me to use the -frepo
flags (gcc-2.95.4 get's confused using -frepo) which
seems to make the code 2-3 % faster than the
gcc-2.95.4 code.

Best wishes,
