../test-skeleton.c: In function ‘legacy_test_function’:

cc1: error: assuming signed overflow does not occur when \

assuming that (X - c) <= X is always true [-Werror=strict-overflow]

Ignoring this warning until the test or compiler is adjusted.
|

Disabled with -Wno-strict-overflow. Attempted -Wstrict-overflow=1,
|
|||
|
|
but it still results in the same warning.
