APAR status
Closed as program error.
Error description
When performing a parallel or distributed build using IBM Rational ClearCase clearmake on a Linux host, the Automated Build Executor (ABE) process may crash with the following message: *** glibc detected *** /opt/rational/clearcase/etc/abe: free(): invalid pointer: 0x091ba4a8 *** While the error message may initially resemble the one in APAR PK66029, analysis shows that a different call stack is behind the issue. If core files are enabled, analysis of the core file may show that /opt/rational/clearcase/shlib/libezrpc.so is the clearcase library before libc.so.6.
Local fix
For a parallel build, where the ABE is directly executed by clearmake, set the MALLOC_CHECK_ environment variable to 0 before starting clearmake. For a distributed build, the environment variable needs to be set on the remote build host. This can be done by: - using a a "wrapper script" in place of the ABE executable, or - Ensuring that the environment variable is set by all ssh sessions coming from the build user. The latter method may be challenging depending on the user shell, and how the ssh daemon is configured to process the user's shell startup scripts
Problem summary
**************************************************************** * USERS AFFECTED: * * Users of IBM ClearCase clearmake. * **************************************************************** * PROBLEM DESCRIPTION: * * IBM ClearCase clearmake on a unix platform may crash with a * * segmentation fault for a specific clearmake case where a * * target has multiple dependencies, and in the building of the * * target, one or more of the dependencies are specifically * * removed. * **************************************************************** * RECOMMENDATION: * ****************************************************************
Problem conclusion
A fix is available in ClearCase versions 8.0.1.11 and 9.0.0.1
