I have found that the GNU C library routines for controlling the signalling of floating point exceptions, which are not really C standard but GNU extensions, do not work in the itanium. Well, they work in the sense that they can suppress the signalling but when activating it, saving and restoring exceptions, etc, they break.
The solution is taking src/h/config.h and surrounding the line that contains #undef HAVE_FEENABLEEXCEPT with something like #ifndef __ia64__ #endif I must say I tested this with ECL 9.10.2 but I think the fix should also work in the versions that Sage is using. BTW, I do not have access to my development machine so this fix has not yet been committed.
