Run the following code on x86 Mono, e.g. on Android:

floatresultF=Add(1.0f,2.0f);doubleresultD=Add(1.0,2.0);Console.WriteLine(resultF);Console.WriteLine(resultD);staticTAdd<T>(Tleft,Tright)whereT:struct{unchecked{if(leftisshort)return(T)(ValueType)(short)((short)(ValueType)left+(short)(ValueType)right);elseif(leftisint)return(T)(ValueType)(int)((int)(ValueType)left+(int)(ValueType)right);elseif(leftislong)return(T)(ValueType)(long)((long)(ValueType)left+(long)(ValueType)right);elseif(leftisushort)return(T)(ValueType)(ushort)((ushort)(ValueType)left+(ushort)(ValueType)right);elseif(leftisuint)return(T)(ValueType)(uint)((uint)(ValueType)left+(uint)(ValueType)right);elseif(leftisulong)return(T)(ValueType)(ulong)((ulong)(ValueType)left+(ulong)(ValueType)right);elseif(leftisbyte)return(T)(ValueType)(byte)((byte)(ValueType)left+(byte)(ValueType)right);elseif(leftissbyte)return(T)(ValueType)(sbyte)((sbyte)(ValueType)left+(sbyte)(ValueType)right);elseif(leftisfloat)return(T)(ValueType)(float)((float)(ValueType)left+(float)(ValueType)right);elseif(leftisdouble)return(T)(ValueType)(double)((double)(ValueType)left+(double)(ValueType)right);elsethrownewNotImplementedException();}}

It crashes with this runtime assert:

* Assertion at /Users/alexander/dev/runtime/src/mono/mono/mini/mini-codegen.c:2306, condition `sp < 8' not met

I saw that x86 is the only platform where we define MONO_ARCH_USE_FPSTACK to true, that's why we only see it there.
