Package: dpkg
Version: 1.17.19
Followup-For: Bug #766242
Hi,
I'm also suffering from this bug. As I do not have dpkg symbols, the
gdb backtrace is not really useful. I give you nonetheless in case you
still have the debug symbols: with the adresses in the backtrace, you
will be able to find the functions.
Note that I've been hit by this big several times today while doing a
relatively important upgrade on my system (about 900 packages). Sometimes (not
sure always), C-c does not do anything. I must kill (SIGTERM) dpkg to stop it.
Regards,
Vincent
