[jira] [Created] (BEAM-9233) Go: unregistered Go functions fail when using -buildmode=pie -ldflags=-w

Ian Lance Taylor created BEAM-9233:
--------------------------------------

             Summary: Go: unregistered Go functions fail when using -buildmode=pie -ldflags=-w
                 Key: BEAM-9233
                 URL: https://issues.apache.org/jira/browse/BEAM-9233
             Project: Beam
          Issue Type: Bug
          Components: sdk-go
    Affects Versions: 2.18.0
         Environment: GNU/Linux
            Reporter: Ian Lance Taylor


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.
