Bug description

raising exception from C code concatenates backtrace with backtrace from previous raise if using 4.03.0+flambda

Steps to reproduce

$ opam switch 4.03.0; eval opam config env; make clean && make foo && ./foo
rm -f *.o *.cmx *.cmi foo
cc -c -o stub.o stub.c
ocamlopt stub.o foo.ml -o foo

$ opam switch 4.03.0+flambda; eval opam config env; make clean && make foo && ./foo

To setup the new switch in the current shell, you need to run:

eval opam config env
rm -f *.o *.cmx *.cmi foo
cc -c -o stub.o stub.c
ocamlopt stub.o foo.ml -o foo
