Expected behavior

r2 analyzes and exits.

Actual behavior

r2 takes quite a long time to analyze and exit.

Steps to reproduce the behavior

• build radare2 (./sys/install.sh)
• r2pm install evm
• run time r2 -a evm -AA -Q $FILE. It may take quite a lot of time during Emulate code to find computed references (aae) the procedure, on one of my machines it took almost 1 hour on one of the seeds; on the other hand, when no arch is specified, time r2 -AA -Q $FILE exits immediately. The uploaded archive contains the sample input files.
