This is either happening because there's a bug in the program or a bug in SAFECode. I'm guessing it's a bug in the SAFECode runtime since you're seeing the "Fault!" message. Can you do the following: 1) Edit runtime/DebugRuntime/PoolAllocatorBitMask.cpp and comment out the code that calls sigaction(). This will disable the runtime's catching of signals. 2) Recompile the library, reinstall it (if you used "make install"), and recompile your program with SAFECode. 3) Use gdb to run your program. When it crashes, can you send me the stack trace? -- John T. > > Thanks! > > > > Program received signal EXC_BAD_ACCESS, Could not access memory. > Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000016 > 0x00007fff860a8065 in mcount () > > > > SAFECode: Fault!
