ok, looks like it fixed it

warning! dont try to manually do the pointer wrapping, ruby already does it
for you! heheh ;)

i'm pretty sure i've tracked down the cause, this is my first time embedding
ruby and writing classes in c++,

so i didnt know you could override the singleton method new for a class, to
do the Data_Make_Struct,

so i was wrapping an outer 'husk' object with a member variable @data which
was pointing to a Data_Wrap_Struct around my c++ object created with new

pretty nasty, and i have no idea how the gc would have interpreted this (as
i did no marking)

now that i've deciphered how everything should work, my matrix/vector
classes should be as efficient as they should have always been with ruby

i'll post back when i have results, cheers

Can you reveal some of this code ?

OK
