>Description:
- gcc dumps core at odd/random places during the compile process.
- depend generates unreasonable line numbers (>200,000), and
appears caught in an infinite loop, thrashing on an "invalid"
dependency.
System under reasonable load (LAVG == 3.53/4.02/3.10). Running
in single user mode, doing a buildworld. Other utitilies,
notably sendmail, exit with sig 11, at random times. No kernel
panic generated (wish it would.)
>How-To-Repeat:
make CFLAGS="-O2 -m486 -pipe" -j 4 buildworld
>Fix:
Unknown. VM frobbing?
