--- Comment #5 from Daniel Fruzynski <bugzi...@poradnik-webmastera.com> --- > There is nothing to indicate that the first call to memcpy() in comment #0 > overlaps so -Wrestrict doesn't warn for it. I thought that fix for bug 83373 will somehow help here. gcc could guess that memcpy will copy from 1 to 15 bytes, which may overlap destination. In fact this could help in all cases here except last memcpy.
