William,
Using gcc-4.2.2, sage-2.8.14 builds and passes all tests on my
x86-Linux (pentium4-fc6) box.
***
On ia64-Linux, it fails to build with an Internal Compiler Error
when compiling flint-0.9-r1075.p1/ZmodF_mul.c; specifically
the compile line is
gcc -std=c99 -I/home/kate/sage/sage-2.8.14-ia64-Linux/local/include/
-I/home/kate/sage/sage-2.8.14-ia64-Linux/local/include
-I/home/kate/sage/sage-2.8.14-ia64-Linux/local/include -funroll-loops
-fexpensive-optimizations -fPIC -O3 -c ZmodF_mul.c -o ZmodF_mul.o
I isolated and reported the problem to the gcc folks (bug # 34266),
the problem goes
away if either -funroll-loops is removed, or if optimization is
reduced from level 3 to level 2.
The bug has been fixed in gcc-4.3-20071123.
Unfortunately trying to build sage-2.8.14 with gcc-4.3-20071123 fails
in cremona-20071124.p2.

On x86_64-Linux (again Fedora Core 6), the following test fails:
