--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:4f34a9e8d5ffcef99a212180d58718b00bdbb7d2 commit r12-8579-g4f34a9e8d5ffcef99a212180d58718b00bdbb7d2 Author: Richard Biener <rguent...@suse.de> Date: Wed Jun 15 10:54:48 2022 +0200 tree-optimization/105969 - FPE with array diagnostics For a [0][0] array we have to be careful when dividing by the element size which is zero for the outermost dimension. Luckily the division is only for an overflow check which is pointless for array size zero. 2022-06-15 Richard Biener <rguent...@suse.de> PR tree-optimization/105969 * gimple-ssa-sprintf.cc (get_origin_and_offset_r): Avoid division by zero in overflow check. * gcc.dg/pr105969.c: New testcase. (cherry picked from commit edb9330c29fe8a0a0b76df6fafd6a223a4d0e41f)
