gcc stack trace and preprocessed header file
I have encountered a header file in the wild (that file being
boost/parser/parser.hpp) that compiles as a header unit without error message,
but causes a segfault when imported as a header unit. The preprocessed header
file is rather long; the C++ source file that imports it is literally just a
single import statement. I have attached the stack trace from gcc, the
preprocessed header file, and the C++ that demonstrates the problem.
