H8SX port having problems in _User_extensions_Thread_create()

[Steven Grunza]

There's a line in cpukit/score/src/userextthreadcreate.c in the function
_User_extensions_Thread_create() that reads:

      status = (*the_extension->Callouts.thread_create)(
_Thread_Executing, the_thread );

This appears to be calling _libc_create_hook() with the first argument
set to 0x00487eb0 and the second argument set to 0.

0x00487eb0 is the value of the_thread and appears to be somewhat sane.
A dump of the structure is below.


Where can I find the documentation on _libc_create_hook()?  I'm not
certain it should be getting called at this point (the crash happens
early in the startup process somewhere between the calling of this
function and it's return.

Any help appreciated.




Here's the dump.  It looks better on-screen but inserting graphics into
e-mail doesn't always work well for communities with *nix, Windows, and
Mac members.
