Yes, it's sad Precise's gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) is still
broken.
If you want to (re)build MPFR with that, use (just) '-O2', or '-O3 -fno-
tree-vectorize'.
Or (build and) use any of FSF's / vanilla GCC 4.7.{0,1,2,3} or 4.8.0 ...

You mean current svn trunk?
I don't get this error with (released) GCC 4.6.3 nor 4.7.0, just with
Ubuntu's 4.6.3-1ubuntu3.
Also your test case from bugzilla works for me with both of these.

Maybe, but you'll probably keep getting duplicates of this bug with the

Similar for Singular (3-1-3-3): g++ / cc1plus crashes with "-O3", builds

Hopefully Precise won't ship with a broken compiler... Haven't had such

It doesn't crash with "-O3" replaced by "-O2" (still with
"-march=native"); also MPFR passes its test suite ('make check') with
these settings / that build.
