This only checks for exit code equals to 128. You should also check for
exit code greater than 128, for example 255.

This test looks OK, using -1 as representative of negative exit code.
However, wording of test name can also be 'bisect run fails with
negative exit code'.

Actually I am not sure that it makes sense to test an exit code
smaller than 0, as POSIX exit codes are between 0 and 255 (included).

For example:

$ bash -c 'exit -1'; echo $?
255

$ dash -c 'exit -1'; echo $?
dash: 1: exit: Illegal number: -1
2
