Seems to be incomplete:

→ ./find-dbgsym-packages /usr/lib/chromium/chromium
BUG: id='9b43003ffd70d8db@0x34c' at ./find-dbgsym-packages line 224.
→ 

There was one more line where 40 was hardcoded:

@@ -217,7 +218,7 @@ sub parse_eu_unstrip
 if ($id eq '-') {
 warn "W: No build-ID for $name\n";
 next;
-} elsif ($id =~ /^([[:xdigit:]]{40})[@]/) {
+} elsif ($id =~ /^([[:xdigit:]]+)[@]/) {
 $id = $1;
 } else {
 die "BUG: id='$id'";

I assume you just missed that line when pasting the bug report.
Anyway, I committed that patch with that line in your name. Hope,
that's ok.

Will be part of the next upload of debian-goodies.

Regards, Axel

Oh, ok, indeed, thanks!

The part of the regex that matches the build-id only recognizes 40-char
(160-bit) build-ids, and the above uses a 16-char (64-bit) build-id.
