#1156: usleep hangs indefinitely when using -threaded
-------------------------------+--------------------------------------------
Reporter: Eelis | Owner:
Type: bug | Status: new
Priority: normal | Milestone:
Component: Compiler | Version: 6.6
Severity: normal | Keywords: usleep threaded unistd
Difficulty: Unknown | Testcase:
Architecture: x86_64 (amd64) | Os: Linux
-------------------------------+--------------------------------------------
Consider the following two-line program.
{{{
import System.Posix.Unistd
main = usleep 1000000
}}}
When compiled without -threaded, the program nicely sleeps for one second,
as expected. When compiled with -threaded, however, the program simply
hangs.
