  I've recompiled asterisk with #define LOW_MEMORY in frame.c and it still
crashes, but probably at some other place. It looks that ReceiveFax generates
some invalid frames when it is hanging, which is harmful. So, the recommended
workaround doesn't work for me :-(. I'm going to remove LOW_MEMORY again, as it
doesn't help.
