Confirmed from 4.9.3 up to trunk (7.0). Compiling the test with 4.8.5 gives the
error
allocate( mygroup(1)%el(10), source=CBTHII( 12, 1, mymaterial, 1.5) )
1
Error: Can't convert TYPE(cmaterial) to CLASS(cmaterial) at (1)
The change occurred between revisions r201266 (2013-07-26, error) and r201631
(2013-08-09, ICE).
