[ruby-core:48804] [ruby-trunk - Bug #6896][Feedback] Ruby crash bringing default http://localhost:3000 page

Issue #6896 has been updated by mame (Yusuke Endoh).

Status changed from Open to Feedback
Priority changed from Normal to Low

From my experience, this kind of issues is often caused by a bug of the extension library.  
I'd like to know why ibm_db maintainer(s) thought that this is Ruby's bug.

Of course, I cannot deny the possibility of Ruby's bug.
But anyway, I think that only those who has IBM DB2 (you or ibm_db maintainer) can investigate this issue...

The best we can do is offer hint of a solution with looking C-level trace.
But the trace you pasted looks corrupted.  Isn't there a C-level trace?  Could you show us a complete log?

Bug #6896: Ruby crash bringing default http://localhost:3000 page
https://bugs.ruby-lang.org/issues/6896#change-32294

Target version: 
ruby -v: 1.9.2


I reported this previously on the Ruby/Rails ibm_db support page and it was suggested that I post the problem here.

After starting the server with 'rails server' and accessing 'localhost:3000', the expected default page comes up and a few seconds later a popup Window with
"Ruby interpreter (CUI) 1.9.2p290 [i386-mingw32 has stopped working"
and the server appears to have crashed.

On a completely different Windows 7 system I installed Ruby 1.9.2, Rails 3.2.8 and ibm_db 2.5.10.
It crashes Ruby with the same error reported intially.

This is with DB2 V10.1 64-bit.

I can try installing DB2 V9.7 and see if it fails.

It doesn't fail on my DB2 V10.1 32-bit system with Ruby 1.9.2, Rails 3.1.0 and ibm_db 2.5.7.

This time the crash produced some additional information in the command window - no indication that it is a database-related failure, although it doesn't fail with sqllite3.
