Getting backtrace in gdb pretty printer errors

Question

I am using custom prertty printers written in Python in gdb. If the pretty printer throws an exception, I get an error message. However, there is no backtrace, so it can be difficult to figure out the origin of the error. Is there any way to print a backtrace in this case?

Answer 1

Yes, put this into your ~/.gdbinit :

set python print-stack full

Then gdb will print the full Python stack trace for errors like this.
