I'm having a problem with this bug too, but for me the test case in the report
only hangs in rare cases. This hangs every time for me (on x86_64 debian wheezy
with commit f07f442 of GDC built with GCC 4.8-20121209):
import std.stdio, std.parallelism;
void main()
{
writeln(taskPool.reduce!"a+b"([0, 1, 2, 3]));
}
The reason for this is that gdc generates code that doesn't call
atomicReadUbyte(status) on every iteration of the loop in
std.parallelism.TaskPool.workLoop as the source code does, but calls it once
before the loop begins and then uses a stored value inside the loop.
