[argobots-discuss] ABT segfault in MacOS

[Iwasaki, Shintaro]

Hi Luca,

Thank you for reporting an issue. Just a quick confirmation:
0. Just in case, are you using an M1 chip?
1. Can you increase the stack size of ULT (by default 4KB, the following increases it to 100KB) and see if the problem happens?
ABT_THREAD_STACKSIZE=100000 ./your_app.exe
2. Is it deterministic? Does it happen at the same place every time?
3. Maybe it encounters another issue. I'd truly appreciate it if you could send me a program/script that can reproduce this issue.

Best,
Shintaro

Subject: [argobots-discuss] ABT segfault in MacOS

Hi,

I compiled the last git version of Argobots in MacOS, ran the tests and they all passed. However, when running an application I am getting some strange segfault that appears to come from ABT. Does anyone have faced similar issues?
