Zero-sized fields do not get processed by finish_record_type: they're removed from the field list before and reinserted after, so their DECL_SIZE_UNIT remains unset, causing the translation of assignment statements with use_memset_p, in quite unusual circumstances, to use a NULL_TREE as the memset length. This patch sets DECL_SIZE_UNIT for the zero-sized fields, that don't go through language-independent layout, in language-specific layout. for gcc/ada/ChangeLog * gcc-interface/decl.c (components_to_record): Set DECL_SIZE_UNIT for zero-sized fields.

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.
