--- Comment #10 from Jan Kratochvil <jan.kratochvil at redhat dot com> ---
It should affect all functions, not just main.

But then GDB already needlessly expands so many CUs that usually when some
function is needed its CU is already expanded.  So maybe it is seen just
accidentally on one trivial testcase.
