destringize_and_run forgets to initialize all the fields of the cpp_context that it pushes. Later _cpp_pop_context then gets confused when it accesses context->tokens_kind via the call to macro_of_context on context->prev. The first hunk of this patch is the real obvious fix. The second hunk is just an assert that I am adding to err on the safe side. Tested by on x86_64-unknown-linux-gnu against trunk by running the test gcc.dg/gomp/macro-4.c under Valgrind, and bootstrapped. libcpp/ * directives.c (destringize_and_run): Properly initialize the new context. * macro.c (_cpp_pop_context): Assert that we shouldn't try to pop the initial base context, which has the same life time as the current instance of cpp_file.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
