From: Praveen Devarao Date: 2013-07-12T00:06:49+09:00 Subject: cfp-consistency error Hi, I am running Rails test suite with DB2 for providing compatibility with Rails-4. I am continuously running into a crash with cfp consistency error. Interestingly this error is occurring at different places, hence making it difficult to diagnose. Could you let me know why does a cfp consistency error occurs, like ehat conditions can cause this error to be thrown. The C code of the ibm_db driver can be found at http://rubyibm.rubyforge.org/svn/trunk/IBM_DB_Driver/ibm_db.c Could anyone point me to where I can start to diagnose and correct the problem. I am on ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-linux] OS - Ubuntu 12.04.2 LTS gcc version with which Ruby is compiled - gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 Here is the initial stack trace..
