+%%--------------------------------------------------------------------
+%% Author : Kostis Sagonas
+%% Purpose : These tests are intended to test the construction and
+%% matching of binaries using variable sizes
+%% Notes :
+%% - Added test that crashed BEAM compiler
+%% - Added test that crashed when segments of size zero were used
+%% and one that did not convert integers to floats when constructing
+%% binaries.
+%% - Added a construction test which crashed from core because of
+%% problems with the effect flag (2004/11/15)
