--- Comment #9 from Vittorio Zecca <zeccav at gmail dot com> --- Applying the proposed fix and compiling the test case with -fsanitize=undefined I get testcase.c:8:3: runtime error: signed integer overflow: 0 - -9223372036854775808 cannot be represented in type 'long int' testcase.c:9:5: runtime error: negation of -9223372036854775808 cannot be represented in type 'long int'; cast to an unsigned type to negate this value to itself as it should be.
