Obfuscator hangs mid-obfuscation #32

Open EricFowlerHTC opened 9 years ago

EricFowlerHTC commented 9 years ago

I have a file that, when fed to the obfuscator, causes it to hang at this point:

2015-03-30 11:07:41.120 ios-class-guard[20143:4698377] Generating symbol table... 2015-03-30 11:07:41.121 ios-class-guard[20143:4698377] Protocols = 16 2015-03-30 11:07:41.121 ios-class-guard[20143:4698377] Classes = 136 2015-03-30 11:07:41.121 ios-class-guard[20143:4698377] Categories = 16 2015-03-30 11:07:41.121 ios-class-guard[20143:4698377] Methods = 1751 2015-03-30 11:07:41.121 ios-class-guard[20143:4698377] I-vars = 345 2015-03-30 11:07:41.121 ios-class-guard[20143:4698377] Forbidden keywords = 154210

Unfortunately, the history is such that I can't just unmake the last change (don't remember what it was).

Has anyone else seen this? Does anyone know how to get around it?

Thanks

This seems to be related to having an 'unclean' project. It appears / disappears in subsequent builds; it sometimes disappears if I fetch fresh code. So it seems some temporary files are hanging around - ?

If anyone knows, please tell. This is driving me crazy.

Thanks very much
