Hello. With this code:
import std.stdio, std.regex;
void main()
{
immutable numbers = regex(r"\d+");
foreach (match; "a1b2c3d4e5".matchAll(numbers))
writeln(match[0]);
}
compiling gives the error:

I'm not sure, but in the switch you posted, you didn't handle the
DLL_THREAD_ATTACH and DLL_THREAD_DETACH cases, the runtime might
be incrementing the refcount there.
