It isn't a method of an "interface"? interfaces indeed have this issue.
But if it is a normal procedure, then this is odd. A few things you can
- On Windows, use an external linker (option -Xe)
- Try stabs vs Dwarf (Project Options > Debugging)
- Do NOT use smart linking
- Do NOT use any optimization -O...
- Try a diff version of gdb
- Try an older fpc (but keep all else the same). So you know if it is an
issue with current fpc.
I also found a bug report https://bugs.freepascal.org/view.php?id=31599

Someone recently reported they had the opposite problem, where the
debugger would step in, when they actually stepped over. Not sure if
