Finally got around to the forum.
libc++abi.dylib
std::__terminate(void (*)()) or std::terminate()
Fatal Exception: std::bad_alloc
std::bad_alloc
// All falls exclusively in the background, for the last month fell about 70 times. All falls displays the Fabric-Crashlytics. If to look at other threads, there are no exceptions and no signs of falling.
Not so long ago, iOS 12 was released for public use, and our application began a massive falls, only on this version (12+). Before that, the application worked for 2 years without such problems.
Crash is clearly not caught, the search for zombie objects also does not give results. The only thing left to think about is that Apple has changed the internal mechanisms of working with memory (???), which throwing the application out of memory, and due to this all models (and old ones including SE, 5s) work 2 times faster, as it was announced at the conference.
I understand that these falls depend directly on the project and its configuration, but still, can you give a push in which direction to dig and look for problems?
