Running the demangler's testsuite with CP_DEMANGLE_DEBUG defined crashes, with: Program received signal SIGSEGV, Segmentation fault. 0x000000000040a8c3 in d_dump (dc=0x1, indent=12) at ../../src/libiberty/cp-demangle.c:567 567 switch (dc->type) (gdb) bt 3 #0 0x000000000040a8c3 in d_dump (dc=0x1, indent=12) at ../../src/libiberty/cp-demangle.c:567 #1 0x000000000040ae47 in d_dump (dc=0x7fffffffd098, indent=10) at ../../src/libiberty/cp-demangle.c:787 #2 0x000000000040ae47 in d_dump (dc=0x7fffffffd0c8, indent=8) at ../../src/libiberty/cp-demangle.c:787 Note dc=0x1, which is obviously a bogus pointer. This is the end of d_dump recursing for a component type that that doesn't actually have subtrees: 787 d_dump (d_left (dc), indent + 2); 788 d_dump (d_right (dc), indent + 2); This fixes the two cases the testsuite currently trips on. libiberty/ 2014-05-28 Pedro Alves <palves@redhat.com> * cp-demangle.c (d_dump): Handle DEMANGLE_COMPONENT_FUNCTION_PARAM and DEMANGLE_COMPONENT_NUMBER.

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. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
