APAR status

• Closed as program error.

Error description

• When using the IBM Rational ClearCase "clearmake" tool to
  perform a build, the tool will crash with one of the following
  errors if the MAKEFLAGS environment variable contains a
  definition of a macro name that is 7 characters long:
  *** glibc detected *** clearmake: free(): invalid next size
  (fast): 0x08f1b3b8 ***
  *** glibc detected *** clearmake: free(): invalid pointer:
  0x08e6bec0 ***
  
  If the macro name in the MAKEFLAGS environment variable is 6 or
  fewer characters, the crash does not occur
  
  The following MAKEFLAGS environment variable will cause
  clearmake to crash:
  MAKEFLAGS=LOADVER=FOO
  
  The following do not:
  MAKEFLAGS=LONGNAME=FOO
  MAKEFLAGS=SHORTY=FOO
  

Local fix

• At this time, the best workaround is to disable glibc's memory
  checking by setting the following environment variable
  MALLOC_CHECK_=0
