When computing size of a static aggregate to decide if it should be transformed into assignments and loops we could have an overflow check. This is mostly harmless, because colossal aggregates will likely crash the application anyway, no matter how we transform them. This was not detected because compiler was built with -gnatg switch that suppresses overflow checks (they are only enabled by an explicit -gnato switch). gcc/ada/ * exp_aggr.adb (Component_Count): Calculate size as an Uint and only then check if it is in the range of Int, as otherwise the multiplication of Int values can overflow. |

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.
