It turns out a single source file is sufficient to trigger the ICE:
Compile:
$ g++ -v -save-temps -DHAVE_CONFIG_H -I. -O3 -mtune=core2 -march=core2
-fomit-frame-pointer -funroll-loops -g -fstack-protector -fPIC -flto -MT
pcrecpp.lo -MD -MP -MF .deps/pcrecpp.Tpo -c pcrecpp.cc -fPIC -DPIC -o
.libs/pcrecpp.o
Using built-in specs.
