More info from VisualGDB output : “../../gdb/cp-namespace.c:825: internal-error: cp_lookup_nested_symbol…” “A problem internal to gDB has been detected.”
The problem seems to go away when I add a breakpoint to my main.cpp. main.cpp is fairly inconsequential within my program (just calls out to another service/function), but must cause VisualGDB to do something “different”.
