Description
Using an alias containing an undefined particle class in cuts causes an segfault once the integration starts. Testcase to reproduce:
model = SM alias visible = charged:hup process test = "e+", "e-" -> "W+", "W-" compile sqrts = 500 cuts = all -0.9 < cos (Theta) < 0.9 [visible] integrate (test)

The program correctly issued an error when the unitialized variable 'hup' was encountered.
This is categorized as an ordinary error, so the program continues. In r1580 I added the code that avoids segfaults; the uninitialized variable is treated as an empty variable. However, the error should have told the user that something was wrong with the input.
