Dear Corinna,
Please note that in net.cc, some kind of
string_size += addrsize_out;
is missing somewhere, which affects a buffer allocation.
See the two locations in diff.
(I do not see well how the two loops (passes) communicate, which might
well be the origin of the problem.)
The problem was discovered with mplayer with some URLs, with DEBUGGING
defined.
Best regards
Jan
