LI75688: COMPILER MEMORY ERROR WITH INLINING

Subscribe

You can track all active APARs for this component.

APAR status

  • Closed as program error.

Error description

  • When compiling very large source files (23,000+ lines) with the
    -Q inlining option, the compiler's memory usage grows and grows
    until an internal compiler error occurs.
    

Local fix

  • Remove the -Q inlining option.
    

Problem summary

  • USERS AFFECTED:
    The problem is with overload resolution with a large number of
    template function candidates.
    
    PROBLEM DESCRIPTION:
    The compiler may run out of memory while processing a large
    number of template function candidates in overload resolution,
    either in a single function body or when attempting to inline
    into a single function body.
    

Problem conclusion

  • The process of selecting and instantiating template function
    candidates for overload resolution has been improved so it does
    not require as much processing and memory at compile-time.
    

Temporary fix
