Bug 925109 – net-proxy/haproxy (all versions) fails tests on arm: HTTP header is incomplete (SIGBUS)

• Status: CONFIRMED
• Product: Gentoo Linux

[Description matoro 2024-02-20 22:06:36 UTC]

Unaligned access is fatal on 32-bit ARM - but more importantly is UNDEFINED BEHAVIOR on all platforms.  A handful of haproxy unit tests expose a codepath committing unaligned access, which crashes on arm with SIGBUS.
