What is the limit of pk for malloc() and mmaps?

[NazerkeT]

Hi there!

I was recently heavily using spike with pk and noticed that I cannot run application with large mallocs like 8MB or more with spike + pk any more. Essentially, simulation fails with either load or store segfaults.

Is there any reason that is coming from pk side for it? If yes, how can I change the current malloc/mmap limitations of the pk? In general, is there any hint or advice do you guys have for it?

Thanks,
Best wishes,

Might be related to your C library, too. Let us know if you find what’s clearly a bug in pk.
