The test was derived from opaque-pointer.c, which contains the single line: struct opaque_struct_t *p_struct; and opaque_struct.c, which looks like: struct opaque_struct_t { int wrapped_value; }; struct opaque_struct_t opaque_internal = { 0 }; What follows is a simplified version of the debug info generated by ICC version 12.0.4.191. */ .file "opaque-pointer.c" .data .comm p_struct,8,8 .global p_struct .section .debug_info debug_info_seg1: .4byte debug_info_seg1_end -
