APAR status
Closed as program error.
Error description
The XL C++ compiler is spending an excessive amount of time evaluating alias sets.
Local fix
Compile with -qalias=typeptr
Problem summary
PROBLEM DESCRIPTION: The C++ compiler front-end requires excessive amount of time to evaluate alias sets. USERS AFFECTED: Users who have compilation units where a char or unsigned char pointer has been cast to another type and dereferenced.
Problem conclusion
Problematic cast shadows involving char variables are now grouped into existing nodes that collapse the alias graph and avoid cycles.
Temporary fix
