--- Comment #28 from jimis <jimis at gmx dot net> 2012-05-20 10:41:28 UTC --- The issue seems to be resolved with these 3 defines, thanks for helping. I now get an ICE at a much later phase which is probably unrelated. I'll try some more recent snapshot later and file a separate bug if it persists. The ICE is: configure:15628: ./gcc/gfortran -B./gcc/ -B./hppa2.0-unknown-linux-gnu/bin/ -B./hppa2.0-unknown-linux-gnu/lib/ -isystem ./hppa2.0-unknown-linux-gnu/include -isystem ./hppa2.0-unknown-linux-gnu/sys-include -c conftest.f >&5 init2.c:52: MPFR assertion failed: p >= 2 && p <= ((mpfr_prec_t)((mpfr_uprec_t) ~(mpfr_uprec_t)0)>>1)) <built-in>:0:0: internal compiler error: Aborted configure: failed program was: | | program foo | real, parameter :: bar = sin (12.34 / 2.5) | end program foo
