Re: Wireshark drops core on Floating Point Exception

["Thomas Laus" <lausts%acm.org@localhost>]

List:

I re-purposed my wife's old laptop into a tool that I plan to use for network 
monitoring and packet filter queue tuning.  This was a clean disk virgin load 
of NetBSD 6.1.5 and only the Fluxbox screen manager was loaded from a package 
after the initial install.  I next performed a pkg_add for Wireshark.  The 
following installed libraries were newer than the prebuilt package so the 
Wireshark program refused to start:

libkrb5
libpthreads
libpcap

I updated my pkgsrc tree and built and installed the program from source in 
order for the program to find the existing updated library files.  Wireshark 
drops core on the a floating point error but Tshark component runs as 
expected and I was able to capture and analyze a packet filter log in pcap 
format.

I started the gdb debugger to gather more information:

(gdb) target exec /usr/pkg/bin/wireshark
(gdb) run
Starting program: /usr/pkg/bin/wireshark 

(wireshark:203): Pango-WARNING **: failed to choose a font, expect ugly 
output. engine-type='PangoRenderFc', script='latin'

(wireshark:203): Pango-WARNING **: failed to choose a font, expect ugly 
output. engine-type='PangoRenderFc', script='common'

Program received signal SIGFPE, Arithmetic exception.

Here is the startup DMESG from my system that shows the processor type and 
some additional information:

This is the Wireshark pkgsrc information:

I contacted the Wireshark port maintainer and he had me run a few tests:

Not really!  It gets the same Pango warnings about failing to choose a font 
that Wireshark does and a lot of little squares but no text.  There must be
some additional dependencies that are not installed when the Wireshark 
package is installed on a virgin system.  The gtk-demo program does not panic 
or abort, however.

If there is any other additional information required, just ask.
