Error description

  • When performing a build using IBM Rational ClearCase's clearmake
    utility, a large number of successive "+=" redefinition of a
    make macro may cause clearmake to use all available process
    memory and abort.
    
    This issue requires approximately 9,000 lines in the form of:
    
    BIG_MACRO += A lot more text to add to BIG_MACRO
    
    to be present in the makefile.
    
    The same makefile will successfully process using the current
    GNU make.
