Issue ID: 24756
Summary: SIGRTMIN and SIGRTMIN+1 previous sigaction are being
silently ignored when set by crt_constructor
Product: D
Version: D2
Hardware: x86_64
OS: Linux
Status: NEW
Severity: normal
Priority: P1
Component: druntime
Assignee: [email protected]
Reporter: [email protected]
Libraries that implement crt0 constructor (crt_constructor) that set SIGRTMIN
and SIGRTMIN+1 get silently ignored after runtime initialisation as it
overrides without checking sigaction previous assignments.
As specified by POSIX, this should be checked and SIGRTMIN+n should have
runtime checks, and not hardcoded.
Runtime, at bare minimum, should assert when silently trying to override a
previous sigaction.
