Bug ID: 254201
Summary: ptrace(): rfork(RFSPAWN) / posix_spawn() reports fork
instead of vfork (+ vfork_done)
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---

reproducer
If the debugged program executes rfork(RFSPAWN) or posix_spawn(), the first
SIGTRAP signal reports PL_FLAG_FORKED instead of PL_FLAG_VFORKED. This is
followed by PL_FLAG_VFORK_DONE, so I guess PL_FLAG_VFORKED was desired.
I'm attaching a simple reproducer. Confirmed on 14.0-CURRENT from end of
January.
