I render a model with PSPGL. But there is a Bus error when called function glDrawRangeElements:

Code: Select all

glDrawRangeElements (mode=4, start=53, end=464, count=1884, type=5123,
    indices=0x8a28ff0) at pspgl_varray_draw_range_elts.c:199
199             __pspgl_varray_draw_range_elts(mode, type, indices, count, start
, end);
