>From the dump and
floatformat.c:529:2: internal compiler error: Segmentation fault
dto = ldexp (1.0, exponent);
wmfire.c:559:6: internal compiler error: Segmentation fault
psi = i * 3.14 / 20.0;
it looks that the segfaults happen on some computations of floating
point numbers in compiler itself. I suspect mpfr libraries of which
functions are used in the dump.
Which version of mpfr/gmp is used for compilers? mpfr has self
test and you could run it with "make check" in its build directory.
