I tried discover from Studio 12u3 on a small example and got no filenames, line numbers and code display in the discover output, only function names with offsets.
This seems to be caused by the option -xdebugformat=stabs (I borrowed this from a larger project, which needs this). The documentation, however, does not mention such a limitation, it refers only to -g. Is this intentional?
Thanks for the heads up Ruppert.
Yes Discover only works with dwarf format which is default. It will not show line number information for binaries built with -xdebugformat=stabs.
We will file a documentation bug for this issue.
