[Bug c/86137] ubsan runtime error in c-format.c
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86137 --- Comment #1 from joseph at codesourcery dot com --- Yes, this code needs to be fixed to avoid undefined overflow (if argnum > INT_MAX / 10 || (argnum == INT_MAX / 10 && *fcp - '0' > INT_MAX % 10), record that overflow has occurred and don't do the arithmetic on argnum).
