Segfault on rethrow() call without argument

[carlobaldassi]

I have encountered a segfault while running the tests for the ArgParse package on latest julia master (it works fine on 0.4).

To reproduce, just install ArgParse version 0.3.0 (the latest at the time of writing) and run the tests with Pkg.test("ArgParse"). Ignore the deprecation warnings. At test number 5, it segfaults. The culprit is this line where rethrow() is invoked.
I can fix the segfault by adding the argument to rethrow(), from this:

catch err
    isa(err, ArgParseError) || rethrow()
end

to this:

catch err
    isa(err, ArgParseError) || rethrow(err)
end

The segfault message is:

I'm sorry but at this moment I'm not able to produce a reduced test case.
