Hello everyone,
The recent changes to Boost.test on trunk have caused testing failures
on OS X. The problem is that internally an exception is thrown on
destruction of every signal_handler. The result looks like this:
boost/boost/test/minimal.hpp(123): exception "system_error produced by:
::sigaltstack( &sigstk, 0 ) != -1: Cannot allocate memory" caught in
function: 'int main(int, char**)'
The cause seems to be that the implementation of sigaltstack() on
Leopard requires the ss_size of a stack_t structure to be MINSIGSTKSZ at
least.
The attached patch accomplishes just this.
Regards,
Jeroen van der Wulp
