Hi,
After long debugging of my code I’ve found that calling hex::async on an
Actions that allocates some data in the stack results in SEG_FAULT. The same is
not true if I use simple (local) function calls.
Here is my code:
———————————
int test(){
char filename[64*1024];
printf("DONE\n");
return 0;
}
HPX_PLAIN_ACTION(testio)
int hpx_main(boost::program_options::variables_map& vm)
{
hpx::parallel::execution::default_executor fancy_executor(
hpx::threads::thread_priority_high,
hpx::threads::thread_stacksize_large);
testio_action act;
hpx::future<int> out = hpx::async(fancy_executor, act, hpx::find_here());
out.get();
return hpx::finalize();
}
———————————
This code results in a SEG_FAULT in test().
Instead if I use the same function test() as a local call with:
hpx::future<int> out = hpx::async(fancy_executor, &testio);
Works correctly.
What is going wrong using the Action? Should I add any settings to my executor
or to HPX to tell that my actions require a bit more stack allocation?
Thank you,
Steve
