Something strange happened and the body of my previous email was lost. I&#39;ve re-sent it here. The attachments are there.<br><br><a href="http://www.haskell.org/pipermail/glasgow-haskell-users/2008-June/014973.html">http://www.haskell.org/pipermail/glasgow-haskell-users/2008-June/014973.html</a><br>
<br>=====<br><br>Hi,<br><br>I&#39;m seeing the following bug revived in 6.8.2 and 6.8.3: <a href="http://hackage.haskell.org/trac/ghc/ticket/672" target="_blank">http://hackage.haskell.org/trac/ghc/ticket/672</a><br><br>I
use a default definition for class method, one that calls methods of
dependent (super?) classes. Of course I&#39;m embarrassed it took me so
long to realize I didn&#39;t _need_ the class in the first place, I could
just write a plain polymorphic function that calls those methods.
Regardless, looks like a bug to me.<br>
<br>Two files are attached, Test.hs and Vec.hs. Search for &quot;BUG IS
HERE&quot; in Test.hs. There is a class and an instance declaration. Compile
as-is to see the correct result. Comment out the method definition in
the instance declaration to see the bug.<br>
<br>If someone confirms, I&#39;ll open a ticket.<br><font color="#888888"><br>Scott</font>
