            Bug ID: 238084
           Summary: r348115 causes reproducable compiler crash in
                    buildworld or buildkernel
           Product: Base System
           Version: CURRENT
          Hardware: amd64

          Severity: Affects Only Me
          Priority: ---

Compiler call from make buildworld which produces a c++.core

After upgrading from r348059 to r348117 make buildworld fails with a compiler
core dump.
Rebooting with the r348059 kernel and using the r348117 world fixes this.

While bisecting I learned that make buildkernel fails as well if the bug is

Finally the change in base r348115 (review D20356) was the cause.

With a r348114 kernel, the attached ARMTargetParser-5d7a90.sh generates a
ARMTargetParser-5d7a90.o file.
With a r348115 kernel a c++.core.

The corresponding ARMTargetParser-5d7a90.cpp is to big for a attachment
because it is 2.4 MB in size.
