https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227329 Bug ID: 227329 Summary: [PATCH] bin/expr: do not fail with "overflow" if no overflow occurs Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: tobias@stoeckmann.org Created attachment 192294 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=192294&action=edit Patch to fix the issue It is possible to trigger an overflow error message with expr, even though no overflow would occur: $ expr -- -36854775800 - \( -9223372036854775807 - 1 \) expr: overflow $ _ The function assert_minus() verifies subtraction in an invert addition case, which is not correct.
