(My gcc is v4.6.0) It required no modifications. -Robert B. Harris from VA From: jfoug [mailto:jfoug@....net] Sent: Wednesday, September 21, 2011 12:04 PM To: john-dev@...ts.openwall.com Subject: [john-dev] Crash bug on win32-cygwin-x86-any builds This may be 'similar' to what Alex is seeing on the Mac OSX (or may be totally different). This crash ONLY happens on win32-cygwin-x86-any. All other builds, work just fine. I have gotten it to work. If I build john.o without -O2, things work. Otherwise, I get a core, with this type message: john 3692 exception::handle: Error while dumping state (probably corrupted stack) There is a john.exe.stackdump, but there is nothing in there, other than text like the line above (probably corrupted stack). NO other builds I have show this problem. However, if I do a full build, then remove -O2 from the CFLAGS, then rm john.o so it rebuilds just that file, perform the make, and the file is happy as can be. When I run the 'broken' version under gdb (I know nothing about gdb, so this will be a trial and error thing), it simply bails out, listing: Program received signal SIGSEGV, Segmentation fault. 0x0045bb27 in ?? () So it appears GDB is not getting any form of stack frame. Jim. Content of type "text/html" skipped
