Some weird messages from debugger window
Hello, everyone, when I debug my program, why my debugger window always show some message like following
"(Internal error: pc 0x0 in read in psymtab, but not in symtab.)" and "can't find linker symbol for virtual table for `MainWindow' value"
They seems to be warning messages, my program still can work well.
PC stands for Program Counter, and 0x0 is running code from position 0. Sounds to me a use of a null pointer variable. It's an error, not a warning and you should fix it before continuing. It will bite you later if you don't!!
