Wireshark · Wireshark-dev: Re: [Wireshark-dev] ssl dissector errors when debugging

[Brian Vandenberg <phantal@xxxxxxxxx>]

 I just got a plugin I wrote awhile back compiling under 0.99.5 and 
tried to run it from within VS2005's debugger.  I loaded up a dump file 
from tcpdump, then went into preferences & setup the SSL dissector.  As 
soon as I hit apply I received a message saying:

-=-=-=-=-=-=-=-=-=-
Windows has triggered a breakpoint in wireshark.exe

This may be due to a corruption of the heap, and indicates a bug in 
wireshark.exe or any of the DLLs it has loaded.
-=-=-=-=-=-=-=-=-=-

 The output window has the following text:

-=-=-=-=-=-=-=-=-=-
HEAP[wireshark.exe]: Invalid Address specified to RtlFreeHeap( 022B0000, 
04239F68 )
Windows has triggered a breakpoint...<repeat of previous text>
-=-=-=-=-=-=-=-=-=-

 That's from setting the SSL key settings.  Similar things happen 
during the SSL dissection process.  The only difference each time around 
seems to be the 2nd parameter of RtlFreeHeap, otherwise the message is 
identical.  It occurs on lines 975, 977, 979, 981, and 983 of 
packet-ssl-utils.c.

 I vaguely remember something like this happening back when I used to 
debug with VS6, but it wasn't as big a headache.  Usually I could just 
F5 through it a few times after-which I didn't have to fool with it 
anymore, but in VS8 it's quite a pain.

 Anyone familiar with this and/or know how to resolve it?
