Preprocessed source
The following command line never finishes compiling (killed after ~24h of
compiling in the background) on GCC 6.0.0 trunk:
$ g++ -c -g -O2 -fsanitize=undefined -fno-omit-frame-pointer -Wall -W
-D_REENTRANT -fPIC -o .obj/XSDTestSuiteHandler.o XSDTestSuiteHandler.ii
the same command without the -fsanitize option finishes in < 3sec.
