Compile this, link it with ruby lib, execute with a small
ruby program like this one :
puts "Hello World from main Ruby Thread"
And explain why there is a core dump !
– jc
#include <ruby.h>
#include <unistd.h>
static VALUE request_thread (void * data)
{
while (1) {
printf (“thread begin\n”);
sleep(1);
printf(“Thread end\n”);
rb_thread_schedule();
}
return Qtrue;
}
int main (int argc, char * argv[])
{
ruby_init();
ruby_options(argc, argv);
rb_thread_create (request_thread, NULL);
ruby_run();
return 0;
}
I think this should be:
static VALUE request_thread(void * data, void * th);
I think it would be nice if in intern.h rb_thread_create were declared
to take a function pointer to a function taking two pointers, instead of
taking ANYARGS. The ruby API is more type-safe than it used to be, but
still leaves something to be desired when it comes to type safety with
function pointers.

I bet you have compiled with stack-frame-pointer ommision turned on. This is done with -fomit-frame-pointer in gcc, and is the default with MSVC when you choose the “Maximise Speed” optimisation. Frame-pointer ommision does not work with ruby exceptions or threads.

Hi,
Compile this, link it with ruby lib, execute with a small
ruby program like this one :
puts “Hello World from main Ruby Thread”
And explain why there is a core dump !
It works for me. Could you tell me about your platform and the
version of Ruby you’re using.
matz.
Platform Solaris Compiler cc (natif Sun Compiler)
Tru-OS-64 Compiler cc (natif Compaq/HP Conpiler)
I’ll try it on Linux and with gcc.
Best Regards,
JC
