To help us debug your issue please explain:
Compile and link a program that executes event post inside an associate block.
What happened (include command output, screenshots, logs, etc.)
Linking error.
What you expected to happen
I expected the linker to produce an executable program a.out.
Step-by-step reproduction instructions to reproduce the error/bug
$cat link-error.f90
module link_error
contains
subroutine post_event_in_associate
use iso_fortran_env
type(event_type), save :: e[*]
associate( i => 1 )
event post(e[1])
end associate
end
end module
end
$caf link-error.f90

failed to compile.
The linking problem goes away if the use statement and type(event_type) declaration are moved to just after the associate statement and wrapped in block/end block.
