inv(13x13 Array{Float64,2}) crahes 0.3.0-prerelease

[turtleslow]

I'm starting to use julia as an alternative to matlab but have been frustrated by an inability to invert matrices larger than 12x12.

For example, inv(randn(13,13)) crashes julia 100% of the time for me (session quits immediately), while inv(randn(12,12)) works 100% of the time.

I'm running 0.3.0-prerelease+2809 in interactive mode on Windows 8.1 but had the same problem in an earlier julia version. Any ideas?

Really think this is a great project though and looking forward to julia gaining momentum!

That is really strange. Can you run versioninfo(true) and report the output here?

[tkelman]

This sounds a lot like #6504 - are you running 64-bit Julia on a Haswell processor? (versioninfo() will provide enough detail for us to look up the processor family.) If so, try downloading http://sourceforge.net/projects/juliadeps-win/files/openblas-47b22763f8ab0219-x86_64-w64-mingw32.7z and replacing bin/libopenblas.dll with the version from that download.

[turtleslow]

Yes, I believe it is Haswell. Below is the output from versioninfo(true). I will try the referenced file and report back whether that fixed the problem. Thanks for the quick response!

Great! This worked. Thanks a lot!

[JeffBezanson]

Many thanks @tkelman . Closing as dup. Will be fully fixed when we bump openblas.

[tkelman]

Happy to help. It'll have to be an rc3 or full release of 0.2.9, since the fix is only in the openblas develop branch so far.
