When running tests using the "sim" config, the command is launched in non-readonly mode and the text retrieved from the expect command will then replace all LF with CRLF. (The problem can be found in sim_load where it calls remote_spawn without an input file). libstdc++-v3/ChangeLog: * testsuite/27_io/print/1.cc: Allow both LF and CRLF in test. * testsuite/27_io/print/3.cc: Likewise.
