* [Bug fortran/35756] New: incorrect WHERE for functions in ELSEWHERE and overlaps @ 2008-03-29 15:38 dick dot hendrickson at gmail dot com 2008-03-29 15:52 ` [Bug fortran/35756] " burnus at gcc dot gnu dot org ` (4 more replies) 0 siblings, 5 replies; 6+ messages in thread From: dick dot hendrickson at gmail dot com @ 2008-03-29 15:38 UTC (permalink / raw) To: gcc-bugs The following program computes the wrong values for the even (elsewhere branch) of the left hand array. It looks like the function R_MY_MIN_I is evaluated before the store in the WHERE branch happens. The same thing happens if the R_M* functions are external rather than contained.

I am holding off on this for 24 hours because (i) I know that there is an issue with derived types with allocatable components and (ii) I've spent a bit too long looking at some other PRs of yours an have broken my tree in so doing:) It must be bed time!
