Description

If a Go program is built with -buildmode=pie -ldflags=-w, the code that transfers an unregistered function fails. It tries to look up the symbol in the DWARF debug info, but that info has been stripped because of the -w flag. This causes a program crash when calling the function.

I have a patch for this problem that I will send shortly.
