This function claims to remove a single character at index p, but it actually removes p+1 characters beginning at p. So r.erase(0) removes the first character, but r.erase(1) removes the second and third, and r.erase(2) removes the second, third and fourth. This is not a useful API. The overload is present in the SGI STL <stl_rope.h> header that we imported, but it isn't documented in the API reference. The erase overloads that are documented are: erase(const iterator& p) erase(const iterator& f, const iterator& l) erase(size_type i, size_type n); Having an erase(size_type p) overload that erases a single character (as the comment says it does) might be useful, but would be inconsistent with std::basic_string::erase(size_type p = 0, size_type n = npos), which erases from p to the end of the string when called with a single argument. Since the function isn't part of the documented API, doesn't do what it claims to do (or anything useful) and "fixing" it would leave it inconsistent with basic_string, I'm just removing that overload. libstdc++-v3/ChangeLog: PR libstdc++/102048 * include/ext/rope (rope::erase(size_type)): Remove broken function.
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.
