[charles-cooper]

what version / commit of titanoboa and vyper is this?

[Leminkay]

Getting the same error for reverting executions on vyper-0.4.0 branch and vyper@v0.4.0b6. E.g. for a = 3 will throw an error, while for other inputs it will work correctly

import boa

test = """
@external
def foo(a: uint256) -> uint256:
    if a == 3:
        raise
    return a
"""

ct = boa.loads(test)
res = ct.foo(3)
print(res)

[charles-cooper]

@hollowgrahm @Leminkay should be fixed in 50ac0fa9f9b3744c283eb9e21447e8c1b83ccb1e. please re-open if you run into any more issues
