--- Comment #21 from Paul H. Hargrove <PHHargrove at lbl dot gov> --- A build from svn trunk (r207062) completed w/o problems. I see: Configuring in i686-pc-linux-gnu/libsanitizer followed later by checking for necessary platform features... no So the added configure check appears to have functioned as intended. Do I need to test other branches too? -Paul
