Website https://lightroom.adobe.com/learn/tutorial/cf323dc7-5d20-4bb1-8249-616995c41800 crashes on minibrowser when running command ``` __XPC_JSC_validateOptions=1 __XPC_JSC_useWasmLLInt=0 __XPC_JSC_useOMGJIT=0 __XPC_JSC_wasmBBQUsesAir=0 __XPC_JSC_webAssemblyBBQB3OptimizationLevel=2 __XPC_JSC_useBBQTierUpChecks=0 ./Tools/Scripts/run-minibrowser ``` It crashes on function effectiveAddr in B3LowerToAir.cpp when`ASSERT(Arg::isValidAddrForm(offset, width));`in debug mode. A temp fix could be ``` // ASSERT(Arg::isValidAddrForm(offset, width)); if (!Arg::isValidAddrForm(offset, width)) { Tmp a = m_code.newTmp(GP); append(Air::Move, Arg::bigImm(offset), a); append(Air::Add64, tmp(address), a, a); return Arg::addr(a); } ```
