APAR status

• Closed as program error.

Error description

• C++ source  fails to compile with the -qoptimize=3  and up due
  to the lack of the resources:
  1586-491 (U) COMPILER LIMIT EXCEEDED: Insufficient virtual
  storage
  

Local fix

• n/a
  

Problem summary

• Users who have a large test case and who compile at -O3 might
  experience this issue.
  
  The problem was that, the compiler optimizer was creating a lot
  of internal temporaries which resulted in the 'Compiler limit
  exceeded' message.
  

Problem conclusion

• The area of the compiler that causes this issue has been patched
  to use a POP mechanism instead of using internal temporaries.
  

Temporary fix
