The assert is https://github.com/weidai11/cryptopp/blob/master/integer.cpp#L4397.
The particular test that is failing is this one:
https://github.com/weidai11/cryptopp/blob/master/validat2.cpp#L686.

The assert is expected when running the test suite in a debug build.

The assert is present to alert a developer when divide by 0 has
happened. DebugBreak() is called so a developer can inspect the call
stack to see what has gone sideways.

Also see https://www.cryptopp.com/wiki/Assertions.
