I am using ifort 18 beta update 1 on Linux Ubuntu and did observe a severe bug with the SYNC IMAGES statement yet. Can someone confirm that the following program does work with ifort 17 but does not execute if compiled with ifort 18 beta yet?
ifort -coarray -coarray-num-images=2 Main.f90 -o a.out program Main ! if (this_image() == 1) then sync images(*) else sync images(1) end if ! end program Main
With ifort 18 beta I am getting the following runtime error:
forrtl: severe (778): One of the images to be synchronized with has terminated. In coarray image 2 Image PC Routine Line Source libicaf.so 00007EFD79C4D607 for_rtl_ICAF_BARR Unknown Unknown a.out 0000000000403CD4 Unknown Unknown Unknown a.out 0000000000403C62 Unknown Unknown Unknown libc-2.19.so 00007EFD7937BF45 __libc_start_main Unknown Unknown a.out 0000000000403B69 Unknown Unknown Unknown forrtl: severe (778): One of the images to be synchronized with has terminated.

(As an aside: It took some time to identify the source of this error, because I do not use SYNC IMAGES regularly and only together with customized synchronization procedures (using sync memory and atomic subroutines) within the same program.)
