Any error log?

I've tried to build and run the tests using the supplied pro file. Log output from running the tests:

Start testing of AesTest Config: Using QtTest library 5.12.3, Qt 5.12.3 (i386-little_endian-ilp32 shared (dynamic) debug build; by GCC 7.3.0) QDEBUG : AesTest::initTestCase() AESNI Enabled PASS : AesTest::initTestCase() A crash occurred in E:_workspaces\Qt-AES-master\debug\QAESEncryption.exe.

When i run in debug mode, it breaks in function "QByteArray QAESEncryption::expandKey(const QByteArray &key)" on the call "AES_128_Key_Expansion(uchar_key, ret);" in line 185.

When building and running through cmake all works fine.

Turns out, if built with cmake it's without aes_ni enabled.

Hello! The problem is on Qt 5.15.2 mingw32 and it doesn’t matter cmake or qmake, in Qt 5.15.2 x64, Qt 6.5.3 x64 everything works. In all cases the error is here tmp = _mm_xor_si128 (tmp,((__m128i*)key)[0]);
