This bug still shows up in gcc version 9.x and 11.x. But not on version 10.x
I've found the simple work-around to disable the optimization(override CFLAGS
with -O0) and it works.

That removes too many optimizations. As explained in comment 5 [1], it should
be enough to add "-freorder-blocks-algorithm=simple" instead of just removing
all optimizations.

Thank you. Yes I've just tested "-freorder-blocks-algorithm=simple" solution of
gcc 9.x and 11.x with -Os enabled and it works perfectly.
By the way, is it useful for you if I provide .i and .s file with -save-temps?
