preprocessd source, referenced from g++ crash

I'm getting a segfault from gcc (well, g++ actually) when trying to compile the
latest thrift code in their master branch (git://git.thrift-rpc.org/thrift.git
at commit 8554399237e54f2b4d6eaa457f9f8be898b56969).

The output of my make invocation before the segfault looks like this:

libtool: compile:  g++ -DHAVE_CONFIG_H -I. -I../.. -I/usr/include -I./src -Wall -g -O2 -MT TBinaryProtocol.lo -MD -MP -MF .deps/TBinaryProtocol.Tpo -c src/protocol/TBinaryProtocol.cpp -o TBinaryProtocol.o >/dev/null 2>&1
