APAR status
Closed as program error.
Error description
When compiling source containing a _Pragma preprocessing operator, the compiler is entering an infinite loop. No memory is used, so the compile process uses CPU time without ever ending, or hitting ulimits. ===== TEST CASE ===== _Pragma("comment(user,xyz;)")
Local fix
- Comment out _Pragma statement - Remove ';' from _Pragma statment
Problem summary
PROBLEM DESCRIPTION: The xlcentry compiler component encounters an infinite loop if there is an unexpected semi-colon ';' in a _Pragma operator. USERS AFFECTED: Who use _Pragma incorrectly, or incorrectly split a string in the middle of a macro which expands to a _Pragma.
Problem conclusion
The infinite loop was corrected and a warning message is now output for incorrect _Pragma usage.
