Hmm, not from me, unfortunately. Cc'ing the java list for clues.
I won't hang up the main patch for this though.

In that case use a text/plain attachment (which, not having tried it myself,
may require you use a .txt suffix on the patch file). Most mail readers will
show those inline. It's certainly better than having actually corrupt data
sent to the list.

You're still scanning for the .loc line, not the "test.c:28"
comment added by -dA.
To understand the problem, go back to your build tree, edit
auto-host.h and undefine HAVE_AS_DWARF2_DEBUG_LINE. Then
rerun the testsuite with RUNTESTFLAGS=dwarf2.exp.
