Do not decode distribution messages as part of the GC operation.
Distribution messages containing maps may generate heap fragments.

in 'set' with 'write_concurrency'
when inserting default object causes table to grow
and the bucket to split is protected by same lock as the key.

Symptom: VM abort "Overrun stack and heap"
Problem: The temporary bignum created in buffer tmp_big[] will be
part of the GC initiated by TestHeapPreserve, but its size is not
included which can cause the GC to overflow if very unlucky.
Solution: Do not include tmp_big in the GC.

Symptom: open_port() succeeds, port program never starts but instead
seem to terminate with exit_status 150 (EINVAL+128).
When: If the command payload buffer (including the entire environment)
for the port program is between 1 to 4 bytes above the pipe capacity,
which is 65536 bytes on newer Linux, but can be as low as 4096 on older
32-bit Linux.
Since: OTP-19.0-rc1.

Yes this is an ugly workaround. One approach for a better
solution could be to introduce an internal secret atom
tagged as an atom with a unique index, but impossible
to find by string hash lookup/insert.

This makes the time that the tests execute longer, which means
that on systems with low resolution on timers (e.g. windows)
the test is less likely to fail.
|
|
The granualarity of the windows time sometimes makes timer:tc
return 0 as the time taken for the test. Change this to use
the most common time instead.

if node fails to start, just skip testcase

It has to be possible to send trace messages to a port
from non-schedulers threads (specifically from the
sys_msg_dispatcher).

A fix for running 19.0-rc2 on FreeBSD with HiPE enabled.
* erl_mmap.h: disregard MAP_NORESERVE for FreeBSD
MAP_NORESERVE is undefined in FreeBSD 10.x and later.
This is to enable 64bit HiPE experimentally on FreeBSD.
Note that on FreeBSD MAP_NORESERVE was "never implemented"
even before 11.x (and the flag does not exist in /usr/src/sys/vm/mmap.c
of 10.3-STABLE r301478 either), and HiPE was working on OTP 18.3.3,
so mandating MAP_NORESERVE on FreeBSD might not be needed.
See the following message on how MAP_NORESERVE was treated on FreeBSD:
<http://lists.llvm.org/pipermail/cfe-commits/Week-of-Mon-20150202/122958.html>
* erl_mmap.c: disable MAP_NORESERVE for FreeBSD

Remove internal state BOUND from inet_drv
|

- Large Maps could cause a stack overrun during crash dump generation.
- This is a simple workaround until a solution has been implemented.
- The error has no impact on a running system.
