Hi,
using svn revision 30650 I started implementing a dissector.
After adding names to Protocol-Fields
(http://www.wireshark.org/docs/wsdg_html/#id4709795)
wireshark crashed in some cases.
Within Filter-Expression window I navigated to filter names of my
custom dissector.
When wireshark tried to retrieve defined names for a specific field
wireshark crashed.
I found out, that the difference between named fields crashing wireshark and not
were a single line at the end of the data structure containing the
value <-> name relation.
The example says data structure should look like:
static const value_string packettypenames[] = {
{ 1, "Initialise" },
{ 2, "Terminate" },
{ 3, "Data" },
{ 0, NULL }
};
when omitting the last line "{ 0, NULL }"
wireshark crashes.
Does this last line have a ETX functionality ?
Shouldn't there be a better way to check the size/end of this data structure!?
thx
Josef
