[ECOS] Infinite loop when excuting "Hello, eCos World!"

[Kidong Lee <briankdlee at gmail dot com>]

Hello,

I compiled "Hello, eCos World!" Sample Appplication and try to execute on Linux,
It print "Hello, eCos World!" and fall in infinite loop.

I chose linux synthetic target (ecosconfig new linux)

This is my development environment.

$ gcc -v

$ uname -a

Is there any solution about this?
