The failure due to -Werror:
compiler/codeGen/StgCmmExpr.hs:55:1: Warning: Pattern match(es) are overlapped In an equation for `cgExpr': cgExpr (StgOpApp (StgPrimOp SeqOp) [StgVarArg a, _] _res_ty) = ... <no location info>: Failing due to -Werror.
The special case for the new seq primop was below the general
cgExpr (StgOpApp op args ty) = cgOpApp op args ty
and thus would never have been reached.
I moved it above (currently validating) to fix that.
