Hi all,

I have sent this mail before but it was timed unfortunately and got lost
in the 18.02 release.

While testing the IO_MEM session on Linux with ACPI I noticed that the
acpi_drv segfaults when freeing its io memory on
repos/os/src/drivers/acpi/acpi.cc:1304 [1]. The crash happens then in
repos/base/include/base/allocator.h:319 [2] at

> operator delete (obj, dealloc);

I noticed that this is called many times without problems but not from
free_io_mem. Unfortunately I have to admit that my C++ knowledge is
insufficient to really grasp what happens in this expression.
Is there any difference in how io memory is freed or should there be any
(at least on Linux)?
