[EgorBo]

the assert is fired in gtSplitTree

[EgorBo]

@jakobbotsch does it ring a bell to you why gtSplitTree fail here on void COMMA while splitting this tree on the helper call point?

[jakobbotsch]

@EgorBo The IR looks invalid, the type of a COMMA should always be the same as its op2. Where do we create that comma?

[EgorBo]

Where do we create that comma?

@SingleAccretion said it's dead store removal?
