Looks like an initial author of that code (tc@) is not working on Chrome.

dmg_fp has no OWNERS.

pkasting@ and deanm@, you made some changes there. Could you please help to find an owner for the issue?

We want to just kill dmg_fp, see bug 593512 among others.

We are getting a rapidly-increasing number of fuzzing reports about it.

I would support duping everything into one "kill dmg_fp" bug and then actually killing it.  Hopefully strtod() is good enough by now.
