Subject: [ruby-talk:25276] GC question

Hi there!

I'm trying to sort out the garbage collection in a C++ extension, and I keep 
getting these errors from gcc. Ruby is 1.6.4 on Linux.

/usr/lib/ruby/1.6/i586-linux-gnu/intern.h:188: too many arguments to function 
`void rb_gc_mark ()'
clientuserruby.cc:401: at this point in file
/usr/lib/ruby/1.6/i586-linux-gnu/intern.h:188: too many arguments to function 
`void rb_gc_mark ()'
clientuserruby.cc:402: at this point in file

I'm passing a VALUE argument to rb_gc_mark() for each Ruby object my C++ 
object holds. Is that right? 

From digging in the source, it seems that rb_gc_mark actually takes a "void 
*" argument which doesn't agree with the prototype. 

Is this a bug? Or is there a trick to getting such code to compile.

Thanks!

Tony
