<p>If "<font color="#008000">morning</font>" in your sentence below
means that you shutdown your system at the end of the day and
start it up in the morning, a possibility might be that your
memory is being exhausted and was freed making it available again
by the system reboot.</p>
<p>You could be read about memory exhaustion, insufficient RAM
memory, and other segmentation fault causes at the following three
links:</p>
Possible Cause #2-prime: Stack Exhaustion Due to Heap or General

</div>
<div> The problem is solved, but, how I don't
know. I have just re do the initilization in this <font
color="#008000">morning</font>, & it works. I have
encountered the similar problems before. Sometimes it is not
working while sometimes it works...I have no clue why &
how such thing happens..........</div>

<p>Currently, I'm using the source code package
WIEN2k_19.2.tar from the Code download [1] area of the
WIEN2k website but with the WIEN2k_VERSION.patch at [2]
that adjusts the WIEN2k_VERSION file from having version
19.1 to match the version 19.2 information given on the
WIEN2k website. The <span>Segmentation</span> <span>fault
error seems to be particular to your system (Linux
operating system, Fortran compiler, etc.) as I was NOT
able to reproduce the error as seen below:<br>
