It appears that sjlj exceptions are broken (PRs 19774/25266/28493). I'm not sure this is true for _every_ target, but it appears to be true for many.
The real bug is PR28493, not PR19774. The latter (and PR25266 which is related) only affect less common cases, i.e. using alloca or variable-length arrays. Unlike PR19774, which is as old as 3.4, PR28493 is new to 4.1.0 (as you know because you are the reporter).
I think it is low priority only because nobody has yet confirmed it (most likely because most GCC developers work on dw2 targets).
