--- Comment #2 from Tom de Vries <vries at gcc dot gnu.org> ---
Reproduced with trunk and gdb-13-branch.

Doesn't reproduce with gdb-12-branch (executed manually, test-case doesn't
compile that far back):
...
$ gdb -q -batch dw2-prologue-end-2 -ex "b foo" -ex "print &foo_label"
Breakpoint 1 at 0x4004b2: file $src, line 22.
$1 = (void (*)()) 0x4004b2 <foo>
...
which is not surprising because prologue_end support was only added in gdb 13.
