Proguard crashes with "Proguard returned with error code 1" and this crashes in the console:

I narrowed it down to a catch try block to throw an IOException. If I comment that try catch block, then it shows this error for another IOException try catch block elsewhere in the application. If I comment on this option, it will be successfully created.
Thus, in both cases, the proguard seems to break into a catch catch IOException block. These blocks were in code in previous builds that went through proguard without any problems.
In addition, there are other catch IOException blocks that give no errors.
I tried this with proguard 4.5, 4.6 and 4.7, and all failed.
Any ideas?
thank
