Why do my stack traces look like this? How can I get more informative ones?

[pineapple via Digitalmars-d-learn]

I'm getting a RangeError and the stack trace is being 
spectacularly unhelpful in debugging  the problem, because it 
looks like this:

core.exception.RangeError@E:\Dropbox\Projects\d\lib\wip_ansi_2.d(78): Range 
violation

0x0040A240
0x00402E37
0x00402B5E
0x00402985
0x00402F29
0x0040C3A3
0x0040C367

0x758533AA in BaseThreadInitThunk
0x77699F72 in RtlInitializeExceptionChain
0x77699F45 in RtlInitializeExceptionChain
How can I fix this, and get something human-readable?
