I don't think so.

Do:

 C-hfeval-expression<RET>

You'll see:
--snip--
If `eval-expression-debug-on-error' is non-nil, which is the default,
this command arranges for all errors to enter the debugger.
--snip--

i.e. when you do eval expression, debug-on-error is temporarily set to t unless 
eval-expression-debug-on-error is set to false.
