.bc file that is causing the error

While trying to compile llvm-gcc (branches/release_26) against the LLVM 2.6
branch, I encountered the following error:

[..]./gcc/xgcc -shared-libgcc [...] -fno-implicit-templates -Wall -Wextra
-Wwrite-strings -Wcast-qual -fdiagnostics-show-location=once
-ffunction-sections -fdata-sections -g -O2 -D_GNU_SOURCE -c
../../../../llvm-gcc/libstdc++-v3/libsupc++/eh_personality.cc  -fPIC -DPIC -o
eh_personality.o
Personality function should be set!
UNREACHABLE executed at
/home/gman/code/codedgers/morpher/src/lib/CodeGen/MachineModuleInfo.cpp:298!
../../../../llvm-gcc/libstdc++-v3/libsupc++/eh_personality.cc:759: internal
compiler error: Aborted

This happens both with and without '--disable-bootstrap'. Trunk llc is able to
handle the problematic .bc file, though.
