Hello,

I'm getting a "test.rb:46: stack level too deep (SystemStackError)"
when defining three or more functions for a module, which is created
& given to Ruby via the Ruby C API.

## begin extra info ##

The test.rb (actually "samp/test.rb") file and the remaining source
code is available in a Subversion repository at RubyForge:

svn checkout -r21 svn://rubyforge.org/var/svn/ruby-vpi/trunk
- -or-
<http://rubyforge.org/plugins/scmsvn/viewcvs.php/trunk/?root=ruby-vpi&path...

Also, I run "make ivl" inside the "samp/" directory to run the
sample test bench ("test.v" and "test.rb").

Finally, I am using this Ruby version:
ruby 1.8.3 (2005-06-23) [i486-linux]

## end extra info ##

In particular, the error occurs when I register a third module
function with Ruby C API inside line 25 of the file
"src/RVPI.cin":

// register the VPI module
RVPI__rModuleDef = rb_define_module("VPI");

rb_define_module_function( // first func
RVPI__rModuleDef
, "relay_verilog"
, RVPI_rb_relay_verilog
, 0
);

rb_define_module_function( // second func
RVPI__rModuleDef
, "register_task"
, RVPI_rb_register_task
, 1
);

rb_define_module_function( // third func
RVPI__rModuleDef
, "handle_by_name"
, RVPI_rb_handle_by_name
, 2
); // FIXME: causes "stack level too deep (SystemStackError)"

I originally thought the problem was with the third module function
(named "RVPI_rb_handle_by_name") that I was trying to register. But
this was not the case, because the SystemStackError occurred even
when I registered the first module function under a different name:

// register the VPI module
RVPI__rModuleDef = rb_define_module("VPI");

rb_define_module_function( // first func
RVPI__rModuleDef
, "relay_verilog"
, RVPI_rb_relay_verilog
, 0
);

rb_define_module_function( // second func
RVPI__rModuleDef
, "register_task"
, RVPI_rb_register_task
, 1
);

rb_define_module_function( // first func with different name
RVPI__rModuleDef
, "foo"
, RVPI_rb_relay_verilog
, 0
);

What am I doing wrong?

Thank you.

You seem to think you are such a brain, when are you ever going to
contribute to this newsgroup? All I see is a person with so little
self esteem that he gets his jollies by ridiculing. Sad.

I've contributed here for years, way before you ever crawled your way here.
I won't help *you* cause all I see is a sad, pathetic old man who has to
whine and complain that he can't write code (or be bothered to look it up
for himself) and has to nag everyone else into doing it for him. Those
kinds of people are the worst. You don't even try, and that's what makes
you a loser.
