Package: bash Version: 5.1~rc1-2 Severity: normal Dear Maintainer, recently while I was running some tests, I ran into this strange overflow:
$ declare -i n=9223372036854775800; for((i=0; i<15; ++i)); do echo "$i -> $n"; n+=1; done 0 -> 9223372036854775800 1 -> 9223372036854775801 2 -> 9223372036854775802 3 -> 9223372036854775803 4 -> 9223372036854775804 5 -> 9223372036854775805 6 -> 9223372036854775806 7 -> 9223372036854775807 8 -> -9223372036854775808 9 -> -9223372036854775807 10 -> -9223372036854775806 11 -> -9223372036854775805 12 -> -9223372036854775804 13 -> -9223372036854775803 14 -> -9223372036854775802 The integer handled by bash is obviously very large, but I believe that in the event of an overflow it would be better to reset the variable and issue an error flow warning, rather than remain silent.
