Yes. But if it was in a C file, one could compile take that out of libc
sources, and compile it manually with debugging enabled. For comparison:
my test setup for the core dumper consisted out of _write.c, dpmiexcp.c
and the sources for __dj_movedata() and friends, all of them compiled with
full debugging turned on. And the test program itself, of course.

seem to work.
