            Bug ID: 15825
           Summary: [not-a-bug, powerpc-darwin8] bad_alloc during assembly
                    of RecursiveASTVisitorTest.cpp
           Product: Test Suite
           Version: trunk
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: Programs Tests
          Assignee: unassignedbugs at nondot.org

This is not a bug, but should be documented.
On powerpc-darwin8, RecursiveASTVisitorTest causes the system assembler to
bad_alloc/out-of-memory.
System compiler is apple-gcc-4.0.1, and assembler is Apple's GNU as 1.38.
This did not occur before r179583, and was first observed r180052.

This will need to be diagnosed and worked around, I'm afraid.
I cannot resume check-clang without a workaround or fix.
