bug#34320: Fwd: Re: bug#34320: Emacs 26.1: RAM does not get released after quitting Emacs

[René Kuligowski]

For completeness ;-)

  I also checked thoroughly in the VFSes (/sys, /proc etc.) and ran a 
mem tracer.  The memory blocks are not freed, but stay allocated, like 
from a forgotten free() call or a severely buggy malloc() call (like the 
common issues with gcc 3.3 and 4.5).

  Since I use gcc 4.4 (quite reliable in my experience), my question 
is: is Emacs 26 using mem alloc calls which are revised/defined in 
C-2011 or C-2015 standards, and not likely to be properly available in 
older compilers?  That might be an explanation, though not exactly the 
„cure“ for the problem.

Regards,
R.Kuligowski

Sorry, the last answer was a bit short.
Reasons why neither is the case:

doing 'ps axf | grep emacs' shows only the grep call itself.  Without
grepping, there is no hint of either emacs or a died/zombie process
eating up memory.

the '+/- cache' line of free shows the amounts I stated, the first one
is always about 1GB larger due to cache buffers.
