digitalmars.D.bugs - exception not caught

Stumbled over the following bug:

# import std.stdio;
# int bb[char[]];
# void main()
# {
#   foreach(char[] s, int i; bb)
#     writef(); // This never gets called, but the bug goes away if it
#               // is exchanged with eg. {}
#
#   bb["a"] = 1;
#
#   foreach(int b; bb)
#     try throw new Error("foo");
#     catch(Error e)
#       // BUG: The exception isn't caught
#       {writefln("Caught error ", e);}
# }

Exchanging the writef() with {} or another simple function call removes the bug.
Removing the "char[] s" loop variable or any of the foreach statements also does
the trick.
