Error description

  • When using optimization, an internal integer to float double
    conversion is causing values to be stored at one memory
    location, but loaded from another location in memory.
    
    For example, in the following listing output, integer 'test' is
    stored on the stack via gr1, but loaded later in the program
    using an offset of gr31:
    
    
    0| 00F608 std F88100B0 1 ST8 test(gr1,176)=gr4
    ...
    0| 0274CC lwa E89F80F2 1 L4A gr4=test(gr31,-32528)
    

Local fix

  • Use a lower optimization level.
