Subject: libstdc++: Fix test for old string ABI
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=561a19c3011f7bde3a41f2a27ea979118e3a2dff;p=gcc.git

libstdc++: Fix test for old string ABI

The COW string doesn't accept const_iterator arguments in insert and
related member functions. Pass a mutable iterator instead.

libstdc++-v3/ChangeLog:

	* testsuite/20_util/from_chars/4.cc: Pass non-const iterator
	to string::insert.
