I haven't had any bus errors while compiling, and I do a fairly good bit of
it on a Sun Ultra 10 (UltraSPARC IIi, not IIIi like the Blade 2500). Do
have a *.c/*.cpp test case I can try to compile that gives you SIGBUS?
Also, what version of GCC are you using?

The problem is that there is no particular case that it Bus Errors on
with gcc. I am right now trying to see if the random Bus Errors have
anything to do with the nouveau driver giving me Kernel unaligned access
errors. So right now I am having this system compile the Linux kernel
without Xorg
I run Xorg with nouveau on that Ultra10 and I too get bus errors from
nouveau, but I do compiles all the time without problem. I understand that
the problem is intermittent -- perhaps it is related to an older GCC
version? I'm using GCC 4.6.x and I have no problems what so ever.

I am running gcc version 4.6.3 so it isn't that. I too wasn't having any
problems with my older Sparc systems, Ultra 5 and Blade 100. Without
Xorg running my kernel compiling hasn't been interrupted by the Bus
error. I have also been running into a known bug with the kernel
The backtraces mention cheetah, which is the UltraSPARC III CPU IIRC.
Also, Blade 100, Ultra 5/10 are single (US-II) CPU systems -- perhaps it is
related to also having SMP? You could try running a UP kernel and see what
happens...

Hello everyone,
I recently got a Sun Blade 2500, and have been trying to track down some
bugs. But one bug that I have constantly noticed is that gcc will
randomly get an Internal Compiler error: Bus error message. Now all I
normally have to do is rerun the compiler and the error doesn't
6 matches
