The check whether reallocation on assignment was required did not handle kind=4 characters correctly such that there was always a reallocation, implying issues with pointer addresses and lower bounds. Additionally, with all deferred strings, the old memory was not freed on reallocation. And, finally, inside the block which was only executed if string lengths or bounds or dynamic types changed, was a subcheck of the same, which was effectively a no op but still confusing and at least added with -O0 extra instructions to the binary. PR fortran/107508 gcc/fortran/ChangeLog: * trans-array.cc (gfc_alloc_allocatable_for_assignment): Fix string-length check, plug memory leak, and avoid generation of effectively no-op code. * trans-expr.cc (alloc_scalar_allocatable_for_assignment): Extend comment; minor cleanup. gcc/testsuite/ChangeLog: * gfortran.dg/widechar_11.f90: New test.
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.
