 Description   

Calling mysql_library_init after a call to mysql_library_end generates a crash.

The crash occurs in the function:
void one_thread_scheduler(scheduler_functions *func,...). On the second call of this function, func is NULL and this is the cause of the crash.

How to reproduce:

  • mysql_library_init(...)
  • mysql_library_end()
  • mysql_library_init(...) --> Crash

It is important to be able to initialize the library several times in order to change the data directory.

talucien, instead of creating a duplicate bug (even the title is identical), you could simply add yourself as watcher or comment on the original MDEV-24071
