Re: [PlayerStage-Users] player 1.6 examples all segfault

[Jeff <wan...@us...>]

Ok, I ran it through valgrind, but I'm not sure which tool I should be 
using.  I just used the memcheck tool.

It actually runs when used with valgrind, i.e. it doesn't segfault.  But 
run by itself, the examples segfault.
