The compiler may crash when compiling array aggregates where the computation of the size produces a very large number that overflows (possibly producing a small result), such as with an aggregate of a type that is an array of arrays, where each array range has close to Integer'Last elements. That can lead to Aggr_Size_OK returning incorrectly returning True, following on to allocating a very large array in function Flatten that blows the stack. The size computation was being performed using type Int, so this was changed to use universal arithmetic. 2019-08-13 Gary Dismukes <dismukes@adacore.com> gcc/ada/ * exp_aggr.adb (Aggr_Size_OK): Compute the aggregate size using universal arithmetic, to avoid situations where the size computation overflows. gcc/testsuite/ * gnat.dg/aggr26.adb: New testcase.

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.
