The "$line $subroutine $filename" part looks good to humans, but the C
compiler should reject it since the string actually ends at the " before
$line.
According to examples/loadables/Makefile.in, caller.def is not compiled
with LOADABLE_BUILTIN defined, which explains why the bug has not failed
the build.
