Hi Szabolcs, Hi Joe,

This report is really showing the power of Linaro TCWG CI. A glibc patch causing a testsuite regression in GCC! Catching such problems by hand is difficult.

This report is not a fluke, it has been confirmed on 2 independent configurations (see https://linaro.atlassian.net/browse/GNU-1084).

Would you please investigate this? And don't hesitate to ask for our assistance in reproducing this.

Kind regards,
