#20563: Cannot compile software (e.g. SnapPy) for sage because sage's gcc is
incompatible with system's as

-----------------------------+----------------------------
Sage comes with its own gcc but uses the system's assembler as. If the
versions of gcc and the gnu assembler are two different, compilation fails
with bizarre errors such as:
Error: no such instruction: `vfmadd312sd offset(%rip),%xmm0,%xmm3'
For example, installing SnapPy (following the instructions from its
website) fails on Mac OS X 10.9 with the latest version of Xcode
compatible with 10.9 for every version of Sage later than 6.7. I have
encountered this problem many times for, literally, years and on both,
Sage and Linux.
I think that if sage continues to ship with its own gcc, it should include
its own gnu assembler as well.
We might even consider including our own linker ld to avoid Mac OS X users
to install xcode.
