unhelpful warning message

[mikestillman]

I have a package that I am writing, and I get the following behavior when loading it. This package loads a number of other packages too.

i1 : needsPackage "StringTorics"
warning: 'intersectionNumbers' redefined
: here is the first use of 'intersectionNumbers'
       : debug with expression   debug 2671   or with command line option   --debug 2671

This appears to be a bug? I try debug 2671 and get nothing useful either. I'll look into this to try to boil the problem down.

I kept getting a similar error in a different context as well, and calling debug didn't seem to do anything.

Here is a minimal example:

newPackage "Foo"
f = x -> x
f = x -> x

The warning message is intentional.

Maybe it should be made clearer, but calling debug with that number should throw you into the debugger when you run the code again.

After I got that error message, I tried what you suggest (call debug with that number), and I now forgot what error message I then got, but it wasn’t useful and didn’t point to the location of the redefinition (or definition).

Maybe try restarting M2 and doing everything the same, except insert "--debug 2671" on the command line.
