This gets an ICE too; compiles with ifort -c

module m_xterm use, intrinsic :: iso_c_binding, only: c_int, c_char implicit none interface function system_timeout_getkey(delay) bind(c, name='Ftimeout_getkey') use iso_c_binding implicit none integer(kind=c_int), intent(in), value :: delay character(kind=c_char) :: system_timeout_getkey end function system_timeout_getkey end interface contains function rawget() result(readback) character(len=:), allocatable :: readback readback = system_timeout_getkey(1_c_int) end function rawget end module m_xterm

For the first ICE - I see that ICE in the 2023.0 compiler and the (hopefully) soon to be announced 2023.1 compiler. However, the nightly build does NOT ICE. This is the version you will see in 2023.2, which should release in the late summer.

For the second ICE - this one is different. And it is getting the ICE in all 3 compilers I tried: 2023.0, 2023.1, and the nightly build. I think this one is BIND(C) related, not strings related. I'll open a bug report on this second testcase.

When I did a recent "apt upgrade" it appears to have installed 2023.1.0. The results have been substantially better but there are at least several more to go. They take a while to reduce down to something small enough to post.

Thanks for giving these your attention.

PS:

That upgrade chewed though a lot of filespace, by the way. Even after cleanup it took around 8GB. That is a heck of a lot for an upgrade.

this issue was fixed in the 2023.2 release.
