Looks like the same issue as gcc 3.4.0. > The same thing happens with 1.9.1.

The issue on gcc 3.4.0 is that if you compile src/modules/lapack/dlamc.f without -ffloat-store it loops forever. I suspect you need to compile it without optimization or with the equivalent of -ffloat-store. It's a separate file in 1.9.1 to make this easier/less penalty and configure sets -ffloat-store if g77 is detected. LAPACK calls Fortran functions to try to force stores, and that worked on versions of gcc <= 3.3.3 (and of course only machines with extended registers like ix86 need the subterfuge). -- Brian D.
