--- Comment #6 from Martin Liška <marxin at gcc dot gnu.org> ---
All right, so it's caused by cdde1:
Assume loop 1 to be finite: it has an exit and -ffinite-loops is on.
-ffinite-loops
Assume that a loop with an exit will eventually take the exit and
not loop indefinitely. This allows the compiler to remove loops that otherwise
have no side-effects, not considering eventual endless looping as such.
This option is enabled by default at -O2 for C++ with -std=c++11 or
higher.
