RE: Segmentation fault on Cursor.drop [ reply ]
2008-08-26 22:50

Well, there are bad news:

* Visual Studio 6.0 is not compatible with Windows Vista

I made it work anyways, but still, it may be a source of problems.

* I think there's a bug in Informix CSDK on Windows Vista.

The problem is the liberation of memory allocated for sqlda structures only on Windows Vista.

Unfortunately I don't have access to support from IBM for the CSDK. I e-mailed them the problem anyways.

I've found a workaround, but I can't make it work cross platform. If you are still interested, please send me an e-mail to explain you the workaround or send you back the binary for Windows Vista.

I'll keep trying to finda better solution

Sorry for the delay.

Unfortunately, I don't have a positive answer yet; but I could replicate the problem. If I can get my development tools to work on Windows Vista this week, I hope to find the bug by the end of the week.

You can help me setting up Visual Studio 6 on your Windows Vista box and building the ruby-informix gem from source.

I'd like to reply sooner, but my day job is absorbing a lot of time recently.

I see.

Give me some hours. I don't use Windows Vista, but coincidentally I've just got a Windows Vista PC today at the office. I'm going to set it up to test Ruby/Informix.

By the way, I'm not sure Ruby is supported on Windows Vista. I'm going to ask about that too.

Gerardo,

The following code will do it:

require 'informix'

Informix.connect('mydatabase@myserver', 'myuser', 'mypassword') do |db|
db.each('select * from project_result where project_id = 32423521') do |row|
puts "#{row[1]}"
end
end

The program segfaults when the cursor is dropped after the inner block yields.

Hi Javier,

could you send me the smallest amount of code that crashes?

You may want to join the mailing list, in case you want more opinions.

Segmentation fault on Cursor.drop [ reply ]
2008-07-01 17:40

I'm getting a segmentation fault every time Cursor.drop is invoked (close works just fine, drop does not).

I'm using ruby 1.8.6 (2007-09-24) [i386-mswin32] on Windows Vista, with Informix CSDK 3.50.TC1 and ruby-informix 0.7.1 (installed via precompiled gem).

Any ideas?
