--- Comment #1 from Jose E. Marchesi <jose.marchesi at oracle dot com> ---
This is most probably a regression introduced by commit 

commit 1944daecca82e70241b24325a1629c50dec9ebd7

    gen: optimize while(0) and while(1)

    2020-05-01  Jose E. Marchesi  <jemarch@gnu.org>

            * lib/pkl-gen.c (pkl_gen_pr_loop_stmt): Optimize while(0) and

The while(1) case is optimized to compile into a single label and BA
instruction.  This breaks the assembling of the break statement, as it assumes
that the state of the macro-assembler is some asm_loop.

A solution would be to introduce a new
pkl_asm_simple_loop/pkl_asm_end_simple_loop that would just
pkl_asm_pushlevel/pkl_asm_poplevel.  That should fix the issue.
