[Bug tree-optimization/31081] [4.3 Regression] Inliner messes up SSA for abnormals

Zero initialization would work, sure.  I was just worried if it wouldn't result
in code pessimization.  The var in the testcase is only unitialized if
exception
is thrown, and exceptions should be exceptional.  But the zero initialization
will be executed even when no exceptions are thrown.  Couldn't we e.g. zero
initialize it only on the EH edges from bbs where it was uninitialized?
