Subject: libstdc++: Fix std::erase_if for std::string with -D_GLIBCXX_USE_CXX11_ABI=0.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e9a62938be080e1d849f6b1e013633584ecace9b;p=thirdparty%2Fgcc.git

libstdc++: Fix std::erase_if for std::string with -D_GLIBCXX_USE_CXX11_ABI=0.

The __cow_string used with -D_GLIBCXX_USE_CXX11_ABI=0, does not provide
erase accepting const_iterator, so we adjust  __detail::__erase.if
(introduced in r16-6889-g3287) to call __cont.erase with mutable iterators.

libstdc++-v3/ChangeLog:

	* include/bits/erase_if.h (__detail::__erase_if): Pass mutable
	iterators to __cont.erase.
