A change made a long time ago has introduced a leak of the secondary stack at run time for unconstrained limited non-controlled arrays in anonymous contexts, because of the lack of a transient scope in these contexts. The large comment preceding the call to Establish_Transient_Scope in the Resolve_Call procedure explains the strategy for build-in-place functions, so the best course of action is probably to revert the commit and to fix the original problem along the lines of the comment. gcc/ada/ChangeLog: * exp_ch3.adb (Expand_N_Object_Declaration): Delete ancient comment. * exp_ch6.adb (Expand_Call_Helper): Do not establish a transient scope for build-in-place functions in anonymous contexts here... (Make_Build_In_Place_Call_In_Anonymous_Context): ...but here instead. * sem_attr.adb (Resolve_Attribute) <Attribute_Range>: Remove obsolete code dealing with transient scopes. * sem_res.adb (Resolve_Actuals): Likewise. (Resolve_Call): Adjust comment on the strategy for transient scopes.
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.
