Bug ID: 75402
Summary: std::condition_variable::wait_until wakes up
constantly
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: nfitzgerald at mozilla dot com
Target Milestone: ---

testcase.cpp
Expected:
The thread calling std::condition_variable::wait_until has no (or very very
few) wake ups until the specified timeout
Actual:
The thread is woken up constantly.
std::condition_variable::wait_until ends up passing a bad timespec as the futex
timeout.
----------------
This test case fails with both std::chrono::steady_clock and
std::chrono::system_clock. I didn't test any other clocks.
