Hi Gilles, were you able to successfully run my T_SUSP test-case after the latest changes? For me this code still causes fatal exceptions:
#include <stdio.h>
#include <sys/mman.h>
#include <native/task.h>
void func(void *arg)
{
printf("you should not see this\n");
rt_task_suspend(NULL);
}
int main(int argc, char **argv)
{
RT_TASK task;
mlockall(MCL_CURRENT|MCL_FUTURE);
rt_task_create(&task, "T_SUSP-test", 0, 10, T_SUSP);
rt_task_start(&task, func, NULL);
printf("deleting...\n");
rt_task_delete(&task);
return 0;
}
This is the output of the locked up system:
