What do you mean by `crash'?
* an exception occurred,
* ruby interpreter segfaulted,
* Excel aborted,
* the blue-screen-of-death occurred, or
* a HDD destroyed physically?

Sorry, I should have been more verbose.

No exception occurs. The interpreter exits with exit code -107374181. Excel stays alive. 

OS is Windows XP SP3. Excel version is 2003 SP3.

Please let me know if more information is needed.
