t/composite test fails, hangs in 6.3.6-8

[mi]

Here is the xterm window-shot, that shows both the failure and the hang. The black composite rectangle is shown, and nothing else is happening -- the machine is idle. Don't remember seeing a hang like this before -- must be due to the "fixing" of the X11-related tests.



Unsetting DISPLAY helps avoid the hang, but leads to a number of new failures:

Please, advise.

Ok, the actual failure of t/composite is, likely, due to the use of HDRI:

Code: Select all

Set(size=>"100x80") ...
Composite(, gravity=>'Center', compose=>'Minus') ...
  mean-error=1,57693614594659e+28, maximum-error=281479271743489
not ok 12
... hang (perl process is sitting in select) ...

But the hang remains unexplainable...

We do not have a solution for the hang at this time. The HDRI PerlMagick tests complete for us with a number of expected failures due to HDRI not clamping pixels (a fix is in the works, not ETA just yet).
