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… The full trace can be found in the
file attached.
