Thanks Julian for the SRU work, the SRU team tries to ensure that every
changeset is documented with a bug/testcase, that doesn't seem to be the
case for * fix-buffer-overflows.patch: fix overflows in vgdb ... is
there any way you could link that to a launchpad bug or at least
document the change
without the patch vgdb crashes in quantal with gcc-4.7 in the testcase
mentioned in the linked bug
I could not reproduce it on precise at the time, but given the simplicity I
think its a good idea to fix the issue there too.
attached a debdiff with better description and bug links

Bugs,
Hi Julian,
nice to see the patch made it into upcoming quatal/12.10.
Any chance to get it also into precise/12.04? After all it's a LTS
release and lot's of machines (especially development machines) won't
make the switch to 12.10 and so would be stuck with the bug for years.

The attached patch is taken from the fix of the upstream bug report. I modified
it slightly to fit version 3.7.0 in the debian/ubuntu package:
- removed the second part as that function does not yet exist in 3.7.0
- Corrected line numbers of chunks to avoid warning when patch is applied.
