* [Bug fortran/58883] New: Segmentation fault when reshaping a allocatable array to allocatable function @ 2013-10-25 20:39 songtao.thu at gmail dot com 2013-10-25 21:52 ` [Bug fortran/58883] Wrong code with realloc on assignment with assigning RESHAPE() to the function result variable burnus at gcc dot gnu.org ` (5 more replies) 0 siblings, 6 replies; 7+ messages in thread From: songtao.thu at gmail dot com @ 2013-10-25 20:39 UTC (permalink / raw) To: gcc-bugs http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58883 Bug ID: 58883 Summary: Segmentation fault when reshaping a allocatable array to allocatable function Product: gcc Version: 4.8.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: songtao.thu at gmail dot com When I reshape a allocatable array to allocatable function output, segmentation fault appears. Test Case1: program main implicit none print *, foo() contains function foo() integer, allocatable :: foo(:,:) integer, allocatable :: temp(:) temp = [1,2,3,4,5,6,7,8] foo = reshape(temp,[2,4]) end function end program However, test case2 works fine: program main implicit none print *, foo() contains function foo() integer, allocatable :: foo(:,:) integer, allocatable :: temp(:), temp2(:,:) temp = [1,2,3,4,5,6,7,8] temp2 = reshape(temp,[2,4]) foo = temp2 ! or call move_alloc(temp2,foo) end function end program Hopefully someone can figure it out.
