Silence one more gcc false-positive.

clalancette commented 4 months ago

gcc 13 has false positives around array-bounds and stringop-overflow, so suppress them here while generating test cases.

@Crola1702 FYI, this should fix #813

813 seems to have the -Warray-bounds warning. What does the -Wstringop-overflow warning look like?

Yeah, good question. Sometimes we get one, and sometimes we get both. In this case, the stringop warning is similar and looks like:
