Wireshark-dev: Re: [Wireshark-dev] Ideas regarding bug 1025?

Hi,

The head of the stack just before the exception is given below.

The actual error is in proto_tree_set_representation at the call:
	g_vsnprintf(fi->rep->representation, ITEM_LABEL_LENGTH, format, ap);

The format has a single %I64x value needed.

The entry to the routine throws an MSVC Runtime Library error dialogue.

Not an area I know much about, but I can reproduce it - if this isnt ringing any bells, drop me a line with where to look next, and I'll give it a whirl.

Hello,

On Linux, I can't reproduce the crash mentioned in
http://bugs.wireshark.org/bugzilla/show_bug.cgi?id=1025
Can someone please try to test this on Windows and maybe provide a stack
trace?

Thanks
     Joerg
