I built an icsref environment on Ubuntu desktop 16.04 lts and all went good. The problem is that running analyze on a real Wago 750-881 prg file never end. System uptime is more than one day with this result log:

/ _/ ___/ // __ / / /

Type if you need a nudge
reversing@icsref:$ history
reversing@icsref:$ analize /home/clientsam/ICSREF/PLC/default.prg
*** Unknown syntax: analize /home/clientsam/ICSREF/PLC/default.prg
reversing@icsref:$ analyze /home/clientsam/ICSREF/PLC/default.prg
Working on /home/clientsam/ICSREF/PLC/default.prg.
DONE: Hexdump generation
DONE: Header analysis
DONE: String analysis
DONE: I/O analysis
DONE: Find function boundaries
(and nothing more)

Given command was: analyze /home/clientsam/ICSREF/PLC/default.prg
default.prg is coming from wago plc memory by ftp get.
It seems that program is locked in an endless loop, and top reveals CPU is 100% most of the time running python command.
Can you give any suggestion?

Many thanks
