image/jpeg: silent failure of jpeg decoding

[mtaran-google]

• What version of Go are you using (go version)? go1.4.2 darwin/amd64
• What operating system and processor architecture are you using? Mac OS X 64-bit Intel
• What did you do?
  • Open this jpeg with image/jpeg (it was produced by a scanner, and it renders fine in browsers, Preview, etc.)
• What did you expect to see?
  • I expected Go to decode the image properly (i.e. white with black text).
• What did you see instead?
  • It decoded the image as a black rectangle, with err == nil

Repro locally with this, though not on the playground.

Please try with Go tip. @nigeltao piped ~all the JPEGs on the Internet through image/jpeg and fixed a number of bugs recently.

It worked at head of master! Are these fixes scheduled for release in 1.4.3 or will it only make it into 1.5?

[minux]

They will only be in Go 1.5.

I'm not sure why that's sad. If this is affecting your work at Google, please mail the internal list for help and we can make sure tip image/jpeg is available to you immediately.
