#11 Segfault with "-n" option

[david Villaume]

Hello,
i'm facing segfault issue on different redhat distrib when using option "-n" after a few time.

For example on : CentOS Linux release 7.1.1503 (Core)

Problem not reproduced without this option.

I attached the debug, may you have a look ?

Thanks

David.

Hi David, thanks for profiling your build. Could you please take a stack dump/backtrace too?

# ...checkout or reuse existing svn directory
make pcapsipdump-debug
ulimit -c 16777216
./pcapsipdump-debug -n ...all the options you would regularly use...
# ...run until it segfaults, and make sure corefile is created
gdb pcapsipdump-debug ...core-file here...
bt
info args
info locals
up
# ...repeat "info locals" and "up" until gdb say "you cannot go up".

Arguments/variables from "info" commands above might contain confidential information. Feel free to replace that with "XXXX".

Ok, I see what happened here:

Program terminated with signal 11, Segmentation fault.
#0  0x00000000004034a0 in main (argc=8, argv=0x7ffd63d33848) at pcapsipdump.cpp:540
540                             ct->table[idx].had_bye=1;

while idx variable at this point is:

idx = -1

Fixed in [r103], thanks for reporting!
