--- Comment #3 from Petr Sumbera <sumbera at volny dot cz> --- I think it uses 'isl' from system: https://github.com/oracle/solaris-userland/blob/master/components/gcc11/Makefile#L216 checking for isl 0.15 or later... yes which should be 0.26 (https://github.com/oracle/solaris-userland/blob/master/components/isl/Makefile#L30) But the same version should use also GCC 14.1 and 12.4 which don't have this problem.
