Nope. But it'd probably help if you sent around a self-contained repro.
Ok, here's a smallish testcase. gdb shows the same problem: an invalid proto expression reference.
This test gives a little more information at runtime. It looks like TranslateToSymbol is called by fusion::transform but is given garbage: Building type list: comma( comma( function( terminal(int_) , terminal(32) ) , function( terminal(int_) , terminal(16) ) ) , function( terminal(int_) , terminal(64) ) ) 3 members for list Translating to symbol: function( terminal(int_) , terminal(-1208424368) ) Also, the test doesn't compile if I remove the const qualifier from the Expr argument to the two TranslateListImpl classes' call operators. I don't know why, but removing them causes a type mismatch. Maybe that's a clue? -Dave
