News of this release:
* 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:
