This fixes UBsan errors like: /usr/include/c++/10/ext/ropeimpl.h:593:9: runtime error: member access within null pointer of type 'struct _RopeRep' /usr/include/c++/10/ext/ropeimpl.h:593:9: runtime error: member call on null pointer of type 'struct _Rope_rep_base' /usr/include/c++/10/ext/rope:556:17: runtime error: reference binding to null pointer of type 'struct allocator_type' /usr/include/c++/10/ext/ropeimpl.h:593:9: runtime error: reference binding to null pointer of type 'struct allocator_type' /usr/include/c++/10/ext/rope:1700:30: runtime error: member call on null pointer of type 'struct new_allocator' /usr/include/c++/10/ext/new_allocator.h:105:29: runtime error: member call on null pointer of type 'struct new_allocator' /usr/include/c++/10/ext/rope:1702:26: runtime error: reference binding to null pointer of type 'const struct allocator' /usr/include/c++/10/bits/allocator.h:148:34: runtime error: reference binding to null pointer of type 'const struct new_allocator' /usr/include/c++/10/ext/rope:1664:39: runtime error: reference binding to null pointer of type 'const struct allocator' /usr/include/c++/10/ext/rope:1665:9: runtime error: reference binding to null pointer of type 'const struct allocator_type' /usr/include/c++/10/ext/rope:725:36: runtime error: reference binding to null pointer of type 'const struct allocator_type' /usr/include/c++/10/ext/rope:614:64: runtime error: reference binding to null pointer of type 'const struct allocator_type' The problem is calling r->_M_get_allocator() when r is null. libstdc++-v3/ChangeLog: * include/ext/rope (rope::_S_concat_char_iter) (rope::_S_destr_concat_char_iter): Add allocator parameter. (rope::push_back, rope::append, rope::insert, operator+): Pass allocator. * include/ext/ropeimpl.h (rope::_S_concat_char_iter) (rope::_S_destr_concat_char_iter): Add allocator parameter and use it. (_Rope_char_ref_proxy::operator=(_CharT)): Pass allocator. |

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.
