Apparently there is a bug on ASIHTTPRequest. If you turn off optimization for ASIFormDataRequest.m ASIHTTPRequest.m everything seems to work.
You turn of optimization by selecting the target project, select the file in "Compile sources" section of the "Build Phases" tab; and add -O0 (capitol O zero).
Everything is explained here
