* signal.c (rb_sigaltstack_size): new. calculate stack size for
sigsegv handler. enlarge value when x86 or x86_64 on Linux. Linux has very small MINSIGSTKSZ size (2048 bytes) and our sigsegv routine need 5KiB at least. [Bug #7141] * internal.h: add declaration of rb_sigaltstack_size(). * vm_core.h: remove ALT_STACK_SIZE definition. * signal.c (rb_register_sigaltstack): replace ALT_STACK_SIZE with rb_sigaltstack_size(); * gc.c (Init_heap): ditto. * vm.c (th_init): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38409 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
