Alastair Donaldson	c5ee1bc7bd	Fix opt fuzzer test harness (#4670) ... The test harness for the opt fuzzer was failing to consider that the input might use a very large id bound, despite no id approaching this bound actually being used. This change modifies the test harness to use the module's id bound, rather than looking through the module for large ids. Fixes: oss-fuzz:42386	2022-01-07 15:03:29 +00:00
Alastair Donaldson	f0351b7bc6	Avoid id bound errors during opt fuzzing (#4658) ... Use a very large id bound when fuzzing the optimizer, and check that the input does not ids that are too close to this bound. This should make it impossible in practice for an id overflow to occur. Fixes #4657.	2021-12-13 10:56:52 +00:00
