Public bug reported:
Ubuntu version:
Description: Ubuntu 12.04.2 LTS
Release: 12.04
Polipo version 1.0.4.1-1.1
With index fix patch in bug #988780
Compiled with -g and -rdynamic
Well, like many others, I got the (or rather, a) random crash bug.
So, I went ahead and compiled it with extra debug info.
I think I need to compile it with -g3 as there are no line numbers in the stack
trace, but hopefully this is enough to track down a little further.
I know that dispose_chunk is in chunk.c from previous experience.
The only assertion in dispose_chunk (both of them) seems to be a null
pointer check in an assert. Somehow, the caller of this function is
erronously giving it a null pointer sometimes.
A potential, short-term workaround would be to have it simply ignore the
free chunk request (by returning early), and maybe log a warning, if a
null is passed in, instead of crashing.
For some reason, apport is not letting upload the report, so I am just
going to attach the output from the crash repport as given by apport-
cli.
There seems to be another form of an assertion failure, so I think this is not
the only thing causing the random crashes.
