The segfault occurs in native_encode_initializer when it is encoding the CONSTRUCTOR for an array whose lower bound is negative (it's OK in Ada). The computation of the current position is done in HOST_WIDE_INT and this does not work for arrays whose original range has a negative lower bound and a positive upper bound; the computation must be done in sizetype instead so that it may wrap around. gcc/ PR middle-end/99641 * fold-const.c (native_encode_initializer) <CONSTRUCTOR>: For an array type, do the computation of the current position in sizetype. |

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.
