That reminded me to commit this libbacktrace patch I worked up a
couple of weeks ago.  Previously if some debug section was missing,
the code could compute the wrong min_offset.  The missing section
would have a zero offset, so min_offset would be set to zero, and
would then be set to the offset of the next section, even though that
one might not be the minimum.  That could lead to a segfault in some
cases, though I don't know if that is the issue that David is seeing.

Anyhow, bootstrapped and ran libbacktrace tests.  Committed to
mainline.

	* elf.c (elf_add): Don't get the wrong offsets if a debug section
	is missing.
