Within the project I used varying snaphots from trunk without any problems. I just retested with my system compiler [gcc version 4.9.1 (Debian 4.9.1-15)] and now also get: internal compiler error: in cp_perform_integral_promotions, at cp/typeck.c:2066 To provide context I attached: a) backtrace b) bisect log c) check script for creduce and bisect d) my reduced testcase At every git-bisect step I did a full bootstrap $dir/$tgt/configure \ --prefix=$prefix \ --program-suffix=-snapshot \ --with-gmp=$prefix \ --with-mpfr=$prefix \ --with-mpc=$prefix \ --with-gnu-ld \ --enable-build-with-cxx --enable-cxx \ --enable-gold --enable-ld=default \ --enable-plugin --with-plugin-ld=ld.gold \ --enable-languages=c,c++ \ --enable-checking=release make -j4 bootstrap make install As you can see in bisect.log some checkouts did not trigger the internal compiler error. I now see one possible defect in my testing methodology: I'm grepping for the line number of the error message. Will retest with the fixed check condition and report back tomorrow if the outcome changes.
