I get no call stack in the cores, and was not able to diagnose it. If john is built with proper -O2 and ONLY john.o is built with -O0, then all of the important parts are properly optimized, john.c does nothing but call initialization code, and then jump to whatever real run() loop code is supposed to be done. I would have rather handled this within cygwin build rules, but at the time could not think how. Now, thinking about it, I think we could do a john_O0.o rule and make it do the same as john.o but simply tack on the -O0. Then, only cyg rules could include that object, instead of john.o Jim. > >0011-vc-cygwin-fixes.diff >0032-build-change-fixing-core-issues-in-cygwin.diff > >cause john.c to be built with -O0 (that is, without optimizations).
