I've encountered segmentation fault at sqlite3async.c:715. The problem
is on sqlite3async.c:712:
nCopy = (int)MIN(pWrite->nByte-iBeginIn, iAmt-iBeginOut); My actual numbers: iAmt = 16, iBeginOut = 2147844072. After subtraction we're getting -2147844056 or FFFFFFFF7FFA8028 in hex which after truncating to int gives 7FFA8028, a positive number. And it blows away the next check if( nCopy>0 ). |
