Yes, and it still prints the "failed assertion" message when run under
valgrind.

Currently it's compiled with -O1.  I'll start it compiling with -O0.

How do I set a watch point on that variable?  If I run "gdb tshark" and then
type "watch except_ch.except_obj.except_dyndata" it says "No symbol except_ch
in current context."  Is that due to -O1?
