Attached is a testcase that fails on x86-64 (and probably other arches as well). In this case, an IFUNC resolver function clobbers xmm0, which is not saved/restored in _dl_runtime_resolve. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
