ccing @ViralBShah for advice and the proper tag :)

[sbromberger]

As an additional data point: I did a completely clean build on the RPi2 and got the exact same error in the exact same place, so it's at least reproducible.

[ViralBShah]

There is a typo in the first line of ARM.inc. A B has snuck into the first line, as the first character. If you fix that, does that change anything? You may have to do a complete build from scratch.

[sbromberger]

Gah. Thanks, @ViralBShah - I don't know how I missed that. Rebuilding now.

[ViralBShah]

Turns out that line was not used anywhere, which is why nothing ever barfed. I have removed it now. Sorry about that.

[sbromberger]

So - that seems to indicate that fixing it will NOT fix this error? :(

[sbromberger]

...and indeed it has no discernible effect. Same error.

[sbromberger]

@ViralBShah @StefanKarpinski - can you help me understand why defining a method dispatch would result in a BoundsError on its parameters, as is apparently happening here? The offending line (102) of version.jl is as follows:

typemax(::Type{VersionNumber}) = VersionNumber(typemax(Int),typemax(Int),typemax(Int),(),("",))

[sbromberger]

OK, so line 102 in the error message isn't really line 102. I added some debugging statements in base/version.jl that moved the method dispatch down a line, and it's still complaining about 102:

LoadError(at "sysimg.jl" line 170: LoadError(at "version.jl" line 102: BoundsError(a=Array{Union, 1}[], i=(1,))))

What version.jl is being used here?

[ihnorton]

I pulled the latest everything and left it building earlier today (Samsung ARM Chromebook). Built fine, but this is with llvm-svn.

[sbromberger]

@ihnorton do you think the issue I'm seeing is llvm-related?

[ihnorton]

No idea. I'm building w 3.5 to see. Was about 1/2 through sysimg last time
I checked. Can't access right now.

Worked fine.

I am using llvm 3.5 just fine on my ARM chromebook. It is quite possible there is some memory corruption elsewhere, or that it is running out of memory. But if it was running out, I would have expected some other error.
