I had never had a problem using latest isl over the past couple of years, so a change in gcc last week introduced the problem. Normally I disable-bootstrap and use last weeks gcc-8 to build this weeks gcc-8 and avoid the extra long bootstrap time. This actually worked, at least with isl-0.18 but the resulting gcc-8 gave ICE errors building latest "pari-gp" and the latest-rc4 Linux kernel. So went back to bootstrapping with (Redhat gcc-7.3.1-2) and discovered the above. Here is failure (using isl-0.18; 0.19 looks same): ... libtool: compile: /home/don/src/gcc-8-20180304-obj/./prev-gcc/xgcc -B/home/don/src/gcc-8-20180304-obj/./prev-gcc/ -B/opt/gcc/gcc-8- 0304/x86_64-redhat-linux/bin/ -B/opt/gcc/gcc-8-0304/x86_64-redhat- linux/bin/ -B/opt/gcc/gcc-8-0304/x86_64-redhat-linux/lib/ -isystem /opt/gcc/gcc-8-0304/x86_64-redhat-linux/include -isystem /opt/gcc/gcc- 8-0304/x86_64-redhat-linux/sys-include -DHAVE_CONFIG_H -I. -I../../gcc- 8-20180304/isl -I../../gcc-8-20180304/isl/include -Iinclude/ -g -O2 -gtoggle -MT isl_factorization.lo -MD -MP -MF .deps/isl_factorization.Tpo -c ../../gcc-8- 20180304/isl/isl_factorization.c -o isl_factorization.o during GIMPLE pass: pre ../../gcc-8-20180304/isl/isl_factorization.c: In function 'isl_basic_set_factorizer': ../../gcc-8-20180304/isl/isl_factorization.c:256:28: internal compiler error: in compute_antic_aux, at tree-ssa-pre.c:2148 __isl_give isl_factorizer *isl_basic_set_factorizer( ^~~~~~~~~~~~~~~~~~~~~~~~ 0x11e6790 compute_antic_aux ../../gcc-8-20180304/gcc/tree-ssa-pre.c:2148 0x11e713b compute_antic ../../gcc-8-20180304/gcc/tree-ssa-pre.c:2364 0x11ec1b1 execute ../../gcc-8-20180304/gcc/tree-ssa-pre.c:4131 Please submit a full bug report, with preprocessed source if appropriate.
