Hello. Sorry if the summary is a little vague, I dont really know a whole bunch
about gcc terminology ;) So anyway, I wrote a simple program in C that computes
the factorials of numbers 1 through 100 (yes, after 7 they get super big). When
this program is compiled as
gcc -ffast-math factorial.c
I get an ICE;
[EMAIL PROTECTED]:~/c$ gcc -Wall -ffast-math factorials.c
factorials.c:8: warning: return type defaults to int
factorials.c: In function main:
factorials.c:24: internal compiler error: in instantiate_virtual_regs_lossage,
at function.c:1442
[EMAIL PROTECTED]:~/c$ gcc -dumpversion
4.0.2
This gcc is from Ubuntu-breezy, gcc-4.0 branch, CVS 20050718. Running on a
Pentium 4.
It told me to report this bug, so here I am :) Regardless of whether this can be
done in a simpler manner, and I'm /sure/ it can, I dont think gcc should die
because of it. The offending code is attached. -save-temps output also attached.
