--- Begin Message ---Package: libuv1 Version: 1.9.1-1 Severity: normal Dear Maintainer, This issue was found during compilation of moar on arm64 where the packaging process is killed after 150mns of inactivity [1]. moar is built on top on libuv1. Long story [2] short, moar hangs randomly while waiting for a zombie gcc subprocess. The SIGCHLD emitted when gcc exits is not used by moar (actually libuv1) On real arm64 HW, this is due to weird SigBlk values (from /proc/$pid/status): SigPnd: 0000000000000000 ShdPnd: 0000000000010000 SigBlk: 929a31e0ee69d200 SigCgt: 0000000180010000 On qemu/arm64, status files also has weird values: SigPnd: 0000000000000000 ShdPnd: 0000000000010000 SigBlk: eb8a0fa374d9e800 SigIgn: 0000000000000000 SigCgt: fffffffff781feff Turns out that moar hang no longer happens on qemu/arm64 when mips-epoll_pwait patch [3] is removed. Note that I could not find a similar change on upstream libuv. Unfortunately, I cannot test this on real HW. Does anyone have an idea on how to fix this issue ?
