Starting from file 20040208-2.c provided in the gcc testsuite I've obtained an
equivalent version performing an abort.
By changing the following two lines:
Internal = x_0 * 0x0.8000000000000000000000000000000000000000p+2L;
x = Internal;
in
x = x_0 * 0x0.8000000000000000000000000000000000000000p+2L;
everything work well.
I've obtained the same bug on gcc 2.96, 3.3.4, 3.4.3 and 4.0.0.
