I have a package (T_LibR280.dpk) that installs some IDE experts. I have a crash in that package and I try to debug it. The problem is that I don't see the line where the crash happens:
[41666AFF]{T_LibR280.bpl} xyz.BaseForm.FormShow + $8B //No line no.
[651BA259]{vcl280.bpl } Vcl.Forms.TCustomForm.DoShow (Line 4564, "Vcl.Forms.pas" + 1) + $14
The package is compiled in Debug mode. All settings seem correct:

The MAP files is present next to the BPL file. Maybe the IDE is looking for it in a different place? Update: The documentation says: "You can discard the RSM file. You do not need a package debug symbol file to debug packages".
