As far as I understand from the documentation setting ASSERT_QUIET_EVAL / assert.quiet_eval to 1 should suppress any error message triggered when evaluating an assertion. 
Either this is not the case or I misunderstand the (rather scarce) documentation on this option. 

Test script:

assert_options(ASSERT_QUIET_EVAL, 1);

Expected result:
Warning: assert(): assert($foo) failed in […] on line 5

Actual result:
Notice: Undefined variable: foo in […] on line 5

Warning: assert(): assert($foo) failed in […] on line 5
