--- Comment #1 from Mikael Pettersson <mikpe at it dot uu.se> 2013-01-11 20:06:03 UTC --- I cut out one line too many in the build log, it's tests/mpq/t-get_d that fails. On the surface the problem started with Jan Hubicka's "Inline heuristic 4/4" patch in r166657: http://gcc.gnu.org/ml/gcc-patches/2010-11/msg01305.html http://gcc.gnu.org/ml/gcc-cvs/2010-11/msg00546.html However, all that did was to bump the default value of early-inlining-insns from 8 to 10. Compiling gmp with gcc-4.5.4 --param early-inlining-insns=10 also causes tests/mpq/t-get_d to fail, so the real problem is older.
