Hi Matthieu,

I don't know when such an error typically happens. I'd be happy if you could share your code with me so that I can closely look at it.

This is just my guess, but perhaps ABT_pool_free() is used; in Argobots, primary ES's pool and schedulers may not be freed before ABT_finalize().
If you free that fifo_wait MPMC pool before ABT_finalize(), an already freed pool is accessed in ABT_finalize(), which may cause the error you wrote.
(It is related to https://github.com/pmodels/argobots/issues/58).
I attached a sample code to explain this issue. Please read the comments in the code if you are interested in it.

I’m getting this error in a program, when calling ABT_finalize:

../src/include/abti_pool.h:238: ABTI_pool_release: Assertion `ABTD_atomic_acquire_load_int32(&p_pool->num_scheds) > 0' failed.

The program only uses the primary ES, it does not create additional ES, however it does replace the primary ES’s pool and scheduler by creating a fifo_wait MPMC pool and passing it to ABT_xstream_set_main_sched_basic, with ABT_SCHED_BASIC_WAIT as sched_predef.

I’m using Argobots 1.0. I haven’t tested with other versions of Argobots. I’m sure I must be doing something wrong somewhere in my code. Could you tell me what I could look for that would lead to such an error?

For additional information, here it the stack trace when the error happens:
