Bug ID: 263825
Summary: Possibly an interesting bug in umtx code
Product: Base System
Version: CURRENT
Hardware: arm64
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: arm
Assignee: [email protected]
Reporter: [email protected]
While testing arm64 Linuxulator's signal trampoline code I found glibc test
which fails on native FreeBSD arm64 (sporadically hangs), but pass on amd64.
Seems to me a some CAS problem.
Unfortunately, I'm not familiar with arm architecture.
Test, adopted to the FreeBSD here:
https://people.freebsd.org/~dchagin/tst-cond25.c
Btw, I tested it under qemu on mac os m1, maybe problem is here?
