Hi,
issue was caused by the patch for PR middle-end/52772, which just
handles dw2. This patch makes sure that for sjlj we add new generated
bb's for dispatching table to loop, too.

PR c++/52924
* except.c (sjlj_emit_dispatch_table): Add bb to loop,
as done for dwarf2.
Bootstrapped for x64_64-w64-mingw32, and x86_64-unknown-linux-gnu.
Later for all languages including Ada and Obj-C++.
Ok for apply?
Regards,
Kai
