Error description
Using -qhot generates incorrect output.
Local fix
Use -qnohot.
Problem summary
In rare cases, users of IPA who use loop optimizations (-qhot) may get incorrect output.
Problem conclusion
An extra temporary variable is introduced by the compiler to guarantee a correct output. Such a variable will only be generated if the compiler suspects that this problem may occur. There's no perfomance impact with the added temporary variable.
