I am using ruby with COM objects. On certain COM function calls the  
output of: COMFunction(arg1,arg2)should produce #N/A, or nil presumably  
in Ruby, however the following occurs:

[BUG] Segmentation fault  
ruby 1.8.5  
(2006-08-25) i386-mswin32]

Any ideas? Is this a ruby problem or an issue with the way WIN32OLE  
handles certain objects?

Thanks

It could be a bug in win32ole. Got a code sample?

Thanks,

Dan

I cannot explain the details, cause i’m a tester and no programmer but  
for WATIR which drives the Internet Explorer with win32ole it is  
recommended to use Ruby 1.8.2. With 1.8.5 i too got segmentation  
faults.

Watir includes a patched win32ole.so library that is compiled to work  
with 1.8.2 only. This is the cause of your error.

The next release of 1.5 will not use this library unless 1.8.2 is  
installed. (This patch is required for the modal dialog support, so  
modal dialogs can only work with watir with 1.8.2 – unless you port  
the patch to 1.8.5.)

How does one port the patch to 1.8.5?

I cant produce an exmaple here since it would require me to upload the  
dll’s. It appears that Win32ole cannot handle arrays of this sort which  
return (#N/A).  
Any ideas?
