Hi
Since new update/upgrade I am unable, with debian amd64 stretch, to preload
a library that lies on the same folder from which I am working. What has changed in amd64 stretch that does no more finds the library and looks elsewhere for a non-existing library? Commands below:

francesco@vaio64:~/servers/cineca/RCM_remote_visualization$ LD_PRELOAD=/home/francesco/servers/cineca/RCM_remote_visualization/libX11.so.6
/bin/ls
libX11.so.6 RCM_linux_64bit francesco@vaio64:~/servers/cineca/RCM_remote_visualization$ export LD_PRELOAD=/home/francesco/tmp/libX11.so.6 francesco@vaio64:~/servers/cineca/RCM_remote_visualization$ ldd /bin/ls ERROR: ld.so: object '/home/francesco/tmp/libX11.so.6' from LD_PRELOAD
cannot be preloaded (cannot open shared object file): ignored.

Therefore, I am unable, at this point, to launch a program for remote visualization (which worked well before the said update/upgrade):

francesco@vaio64:~/servers/cineca/RCM_remote_visualization$ ./RCM_linux_64bitERROR: ld.so: object '/home/francesco/tmp/libX11.so.6'
from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

Grateful for advice

Those LD_PRELOAD paths are different and nothing in your commands
output shows that /home/francesco/tmp/libX11.so.6 really exists. Are you
sure it's there?
