Hi all, When an MVar# primop blocks, it jumps to a function in HeapStackCheck.cmm which pushes a RET_SMALL stack frame before returning to the scheduler (e.g. the takeMVar# primop jumps to stg_block_takemvar for stack adjustment). But these functions directly bump Sp without checking for possible stack overflow, I wonder if it is a bug?
