Last time I have been working on a C++ binary serialization framework that allows to serialize simple data structures with a few lines of code. First, you add AWL_REFLECT macro to all your structures as follows:
#include "Awl/Reflection.h"
#include <string>
#include <vector>
#include <set>
struct A
{
int a;
bool b;
std::string c;
double d;
AWL_REFLECT(a, b, c, d)
};
When I switched to QT 6.7.2 and set QT_ANDROID_TARGET_SDK_VERSION "34" (that is Android 14) my QT app started to crash with the following stack traces:

I installed MacOS Sonoma on HyperV, installed XCode and used the following commands to check compiler and SDK versions:
admin@son ~ % xcode-select -print-path
/Applications/Xcode.app/Contents/Developer
admin@son ~ % xcrun -sdk macosx -find clang
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
admin@son ~ % clang --version
Apple clang version 15.0.0 (clang-1500.3.9.4)
Target: x86_64-apple-darwin23.4.0
Thread model: posix
