segfault in test on nightly

[topolarity]

using AllocCheck
using AllocCheck: AllocatingRuntimeCall, DynamicDispatch, AllocationSite
using Test

@check_allocs mymul(x,y) = x * y
@test_throws AllocCheckFailure mymul(rand(10,10), rand(10,10))

Something about throwing the error + --check-bounds=yes seems to combine to produce this bug.

Run as julia +nightly --project=env --check-bounds=yes mwe.jl to get a segfault:
