Error description
A large Fortran test case produces incorrect result compiled with xlf compiler. It sometimes produces segmentation fault on different machines.
Local fix
In the test case, Use: asum%b = asum%b + a2%b instead of: asum%b(1:n_b) = asum%b(1:n_b) + a2%b(1:n_b)
Problem summary
PROBLEM DESCRIPTION: The problem happens when the following conditions hold: 1. There is an elemental function call and the result is of a derived type which contains an allocatable component. 2. The shape of the result can not be determined at compile time. USERS AFFECTED: Users who use an elemental function returning a result containing allocatable components will be hit.
Problem conclusion
The problem is solved. The compiler now creates a descriptor for the elemental function result and allocates space before taking the function result.
Temporary fix
