--- Comment #6 from Tom de Vries <vries at gcc dot gnu.org> --- Hmm, at r225942 I read: ... [graphite] fix pr61929 This fixes bootstrap of GCC with BOOT_CFLAGS="-g -O2 -fgraphite-identity -floop-nest-optimize -floop-block -floop-interchange -floop-strip-mine". It passes regstrap on amd64-linux. A previous change (https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=213816), replaced isl_int with isl_val because isl_int would be deprecated. Since isl_val has stricter checks, it exposed the bug. In the test case (isl_set_max_val) would return infinity which would remain unchecked. We now check if the value returned is an integer or not, and bail out if it isn't. ... This seems to be a duplicate of PR61929.[ If we mark this as a duplicate, we should re-open PR61929 and mark it as 5 regression. ]
