[aspect-devel] ": internal error: ** The compiler has encountered an unexpected problem.

[Lev Karatun]

Hi Wolfgang,

yes, I was actually trying to do it yesterday -- to compile with level 2
optimization and on 1 core. It actually compiled successfully on 1 core for
both level 2 and 3 optimizations.
Thanks everyone for the help!

Best regards,
Lev Karatun.
