I did some research on why my QT app crashes at the destructor of std::thread on Android 10 devices at the user side with the following call stack:
#00 /apex/com.android.runtime/lib64/bionic/libc.so (abort+160)
#01 /system/lib64/libc++.so (abort_message+232)
#02 /system/lib64/libc++.so (demangling_terminate_handler()+44)
#03 /system/lib64/libc++.so (std::__terminate(void (*)())+12)
#04 /system/lib64/libc++.so (std::terminate()+52)
#05 /system/lib64/libc++.so (std::__1::thread::~thread()+20)
#06 /apex/com.android.runtime/lib64/bionic/libc.so (__cxa_finalize+212)
#07 /apex/com.android.runtime/lib64/bionic/libc.so (exit+24)
#08 /data/app/com.domain.myapp-Rs_sm5VrLR1Jj8QW6oYByA==/lib/arm64/libplugins_platforms_qtforandroid_arm64-v8a.so
and figured out that its likely because std::thread destructor is being invoked while the thread is still joinable at some point of the application execution (thanks to G. M. on stackoverflow.com).

I wrote a simple test that outputs std::memmove speed to the console:
AWT_ATTRIBUTE(size_t, element_count, 1000000);
std::unique_ptr<uint8_t> p_src(new uint8_t[element_count]);
std::memset(p_src.get(), 25u, element_count);
std::unique_ptr<uint8_t> p_dst(new uint8_t[element_count]);
context.out << _T("std::memmove: ");
awl::StopWatch w;
std::memmove(p_dst.get(), p_src.get(), element_count);
ReportSpeed(context, w, element_count);
context.out << std::endl;
And the similar tests for std::memset and std::vector::insert.
(more…)In the code below, static_assert operates on the addresses of local variables, but however MS compiles it and the assertion does not fail:
#include <tuple>
#include <string>
struct A
{
int a;
double b;
std::string c;
};
void f()
{
A a{ 1, 3.0, "abc" };
constexpr auto t1 = std::tie(a.a, a.b, a.c);
static_assert(&std::get<0>(t1) == &a.a);
}
Use the following command to compile this example:
cl /std:c++17 /EHsc a.cpp
I created an unlockable product in Google Play, added billing permission to the manifest:
<uses-permission android:name="com.android.vending.BILLING"/>
and implemented billing in my application, but when I attempted to purchase the product first time I got error ‘This version of the application is not configured for billing through Google Play‘:
