[LLVMdev] llvm-gcc won't bootstrap

Got a strange problem.  With our modified llvm here,llvm-gcc won't
bootstrap.  It fails compiling unwind-dw2.c during translation from
the gcc IR to llvm.  It fails with -O0 -emit-llvm so according to
the docs, this is strictly a frontend bug.  A run of delta produced
an 18 line testcase with nothing remarkable in it.

However, it bootstraps fine using the official llvm sources.  Note
that the llvm-gcc sources used in both builds is identical.

How can this be?
