Help is broken

julia> help(max)
Loading help data...
ERROR: no method start(Nothing,)
 in init_help at help.jl:51
 in help_for at help.jl:125
 in help at help.jl:198

Line 51 of help.jl is a call to evalfile, which has been the subject of some recent issues.

Works for me.

For me it fails with the error above on first use after starting Julia and works after that.

it seems it is a temporary type inference failure, upon deleting sys.ji and rebuilding the system image, the issue should go away for you

[vtjnash]

actually, this is not a type inference failure but a dup of #265

For me it fails with the error above on first use after starting Julia and works after that.

For me, on the second try it just prints the method table, not the help in helpdb.jl.

Yes, I can confirm this works (thanks, @vtjnash). I haven't yet played around enough to figure out the conditions under which one needs to do this.

To clarify, the key point seems to be that deleting sys.ji followed by make acts a lot like make clean without the need to touch the C library.
