lto link error undefined symbol: setjmp

[calvin2021y]

I try build with --target=wasm32-wasi -mllvm -wasm-enable-sjlj and -flto=full

get this error:

undefined symbol: setjmp
undefined symbol: longjmp
nm test.o |grep jmp
         U longjmp
         U setjmp

If I remove -flto=full, all work as expect:

 nm test.o |grep jmp
         U __c_longjmp
         U __wasm_longjmp
         U saveSetjmp
         U testSetjmp
