Summary: buildworld bus error MachineLICM.o for i386 targets
10.1S r283021
Product: Base System
Version: 10.1-STABLE
Hardware: i386
OS: Any
Status: New
Severity: Affects Only Me

Bus error from MachineLICM.o arises during buildworld of i386 pentium3 systems

I perform a build sequence which includes using CPUTYPE's c3-2, pentium3,
prescott (plus a few amd64 worlds). During the last three cycles (about 2
weeks apart) only ONE of the i386 build worlds will fail (none fail for amd64
targets)
They use a common set of scripts where MAKEOBJPREFIX, CPUTYPE, TARGET_CPUTYPE
and -march= or -mtune= variables are changed.
Aside typically each has 4 kernels, also all of these build without error.
The following is taken from the pentium3 failure which occurred last night.
Yesterday if failed for the c3-2 build. Very puzzling.
Hardware: Xeon E3-1230L, build disk SSD (Kingston SV300).
smartctl reports overall health: Passed
