In the testcase for 103534 we get a warning about append leading to memcpy of a very large number of bytes overflowing the buffer. This turns out to be because we weren't calling _M_check_length for string append. Rather than do that directly, let's go through the public pointer append that calls it. PR c++/103534 libstdc++-v3/ChangeLog: * include/bits/basic_string.h (append (basic_string)): Call pointer append instead of _M_append directly. gcc/testsuite/ChangeLog: * g++.dg/warn/Wstringop-overflow-8.C: New test. |
