Hello all, I'm rephrasing my previous question to reflect new findings in my situation in the hopes that someone may have an idea of what's going on here (see thread "Internal compiler error in reload_cse_simplify_operands" from earlier this week). In a nutshell, I have upgraded my machine to a PIV 2.4 GHz processor on a VIA P4B 400 motherboard with 512 MB Samsung 2700 DDRAM. I have a 300 Watt power supply with a ball-bearing fan and a Seagate 40 GB HD. The problem I'm having that I did not see with my PIII is that I'm getting intermittent internal compiler errors when attempting to compile anything (again, see previous thread for an example). I even did a fresh install of the system yesterday in order to rule out something random getting hosed causing problems with my compiler. Through experimentation, I've found that toggling the CFLAGS from -O to -O2 or vice-versa works around the problem (actually, I've had greater success leaving my CFLAGS set to -O2 -pipe and occasionally bringing them back to -O -pipe when I run into an ICE and then setting them back again). My hunch is that some hardware bug is being tickled by gcc somehow. I don't think it's the standard "broken hardware" thing because I've not received any signal 11/7/4 errors at all and the system runs wonderfully. So far it's been up for over 24 hours, compiling ports and running without a hitch. The only strangeness is the compiler's behavior. Also, I should mention that I added options DISABLE_PSE options DISABLE_PG_G to my kernel config but the ICE's still persist, though they seem to be less frequent now. Attached is my dmesg, please let me know if anyone would like any more information about this or if you have any idea what might be going on here.
