[Barrelfish-users] Bug in malloc()/free() ?

[Zeus Gómez Marmolejo]

Hi,

Here I introduce you a pretty simple program:

int main(int argc, char **argv)
{
  void *p;
  int i;

  for(i=0; ;i++)
    {
      p = malloc(65536);
      if (p==NULL)
        USER_PANIC("malloc() returned NULL at %d", i);
      free (p);
    }

  return 0;
}

This is ALWAYS aborting as:

ERROR: myapp.0 in morecore_alloc()
../barrelfish/lib/barrelfish/morecore.c:85
ERROR: vspace_mmu_aware_map fail
Failure: (  libbarrelfish) Out of space in vspace_mmu_aware_map() function
[LIB_ERR_VSPACE_MMU_AWARE_NO_SPACE]
myapp.0 in main() ../barrelfish/usr/tests/myapp/myapp.c:12
malloc() returned NULL at 16382
Aborted

With the latest Barrelfish tree. Are you aware of this?
