New in 2.6: * sigsegv_leave_handler is changed. Previously it was a normal function with no arguments. Now it is a function that take a non-returning continuation function and three arguments for it as arguments. Where you had code like int my_handler(void* fault_address, int serious) { ...code_before()...; sigsegv_leave_handler(); ...code_after()...; longjmp(...); } you now have to write void my_handler_tail(void* arg1, void* arg2, void* arg3) { ...code_after()...; longjmp(...); } int my_handler(void* fault_address, int serious) { ...code_before()...; #if LIBSIGSEGV_VERSION >= 0x0206 return sigsegv_leave_handler(my_handler_tail, arg, NULL, NULL); #else sigsegv_leave_handler(); my_handler_tail(arg, NULL, NULL); /* NOTREACHED */ abort(); #endif } * sigsegv_leave_handler now works correctly on MacOS X. * Support for 64-bit ABI on MacOS X 10.5. * Support for building universal binaries on MacOS X. * Improved distinction between stack overflow and other fault on NetBSD, OpenBSD, FreeBSD, Linux, AIX, Solaris. Contributed by Eric Blake. * GNU gnulib now has an autoconf macro for locating libsigsegv: http://www.gnu.org/software/gnulib/MODULES.html#module=libsigsegv New in 2.5: * Support for MacOS X 10.5. New in 2.4: * Support for GCC 4 on more platforms. * Added support for catching stack overflow on NetBSD. * Improved support for catching stack overflow on Linux, Solaris: Works also when /proc is not mounted or lacks read permissions. New in 2.3: * Support for GCC 4 on some platforms contributed by Paolo Bonzini. * Support for MacOS X i386 contributed by Bruno Haible. * Improved support for Woe32 contributed by Doug Currie. New in 2.2: * Support for new versions of MacOS X contributed by Paolo Bonzini. * Improved support for AIX 5, contributed by Bruno Haible. New in 2.1: * Support for MacOS X contributed by Paolo Bonzini. * Support for Cygwin contributed by Paolo Bonzini. * Support for Linux/ia64 and Linux/hppa contributed by Bruno Haible. * Support for OpenBSD/i386 contributed by Bruno Haible. * Support for NetBSD/alpha contributed by Paolo Bonzini. New in 2.0: * Modernized infrastructure. * Added support for catching stack overflow on AIX 4, HP-UX, and BeOS. * Dropped support for NeXTstep. * The function sigsegv_leave_handler() no longer restores the signal mask. This must now be done by the calling handler (either through sigprocmask or through siglongjmp). New in 1.2: * Support for HP-UX contributed by Paolo Bonzini. New in 1.1: * Catching stack overflow now works on some Unix systems: - Linux 2.2.x with glibc-2.1, - Sun Solaris, - DEC OSF/1 4.0, - SGI Irix.
