How to fix/debug "can't find linker symbol for virtual table"?

[Jean Paul Talledo Vilela]

Working with STM32F429 Discovery board with FreeRTOS and DNP3 firmware running. Need suggestions how to debug this issue.

Basically, I have a board setup with UART interrupts while injecting a byte from UART into a dnp3 Queue buffer, system shows a pointer at INterrupt address.

Compiler does not provide any warnings about code on that module. attaching some screenshots

Looks like an artificial problem, caused by use of C++ :(
