It somehow concludes that asize may be negative and would then cast to
an obscenely large size_t. This produces the following warning:
.../qbytearray.cpp: In member function ‘replace.constprop.isra’:
.../qbytearray.cpp:2579:23: warning: ‘memcpy’ specified bound between 9223372036854775808 and 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Wstringop-overflow=]
2579 | memcpy(d + to, a, asize);

Check for asize > 0 rather than asize != 0.
