Quoting Scott Reese <[EMAIL PROTECTED]>:
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.
Thank you,
Scott
Whenever I've had problems like this, it's been either bad memory, or bad memory
settings in bios. I'd check both of those things.

According to several bug reports on gcc.gnu.org related to cse and p4 I
strongly recommend to all whose using -On (with n>1) to add -fno-gcse
etc. for all cse options.
Of course, any interested can add themself as watcher for each
interested reported gcc bug.
Best,
Jens
