Unable to set breakpoints in vscode

I am developing in a virtual machine passing through DAPlink running on K20DX as debugger connected to an nRF52840 on the Agora target. I am able to flash binaries to the Agora, and I am able to start and run a debugging session. However, I am unable to set a breakpoint anywhere other than the first line in main().

Here is the debug output that is generated starting a debugging session until it reaches main()

Here is the output generated when I attempt to add a breakpoint to line 19:

I've searched for why gdb would report "No line x in file". I tried adding -ggdb to the list of compiler flags but that had no effect. I reduced the compiler optimization from -Og to -O0. This actually allowed me to set breakpoints, but mbed crashes after one pass through the while loop. I think there may be an issue with sleep and the 0 optimization.
