Comment:

 The given program fails to compile with the 7.0 release candidate, due to
 #4418. Working around this problem by adding the fundep {{{pm - pv}}} to
 the {{{PackedMat}}} class, it compiles and gives Core essentially the same
 as the 6.12 Core: no unnecessary constructors.

 With ghc 6.12.3, we get the following core from your file:

Comment(by simonpj):

 So you are saying that 6.12 was good?  What about the 7.0 release
 candidate.  If that's ok too, just close the ticket. (Again I can't see a
 good way to make a regression test.)

 Thanks for the testcase; we'll take a look.

 Default class method not inlined. Class PackedMat has a method unpackMat.
 There is one instance declared. In the attached file, the method
 definitions of that instance are commented out, falling back to the
 default defs. Compile as-is (with -O2) to see the bug. Uncomment the
 instance method definitions to see the desired behavior.

 possibly related to #672
