[Bug 1923701] [NEW] internal compiler error: in int_mode_for_mode, at stor-layout.c:403

[Hai]

Public bug reported:

Currently I am trying to compile CASTEP package. However, I face with
this problem.

I am using "gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04)"

I try to command "make". The problem is shown as below.

"make -C "obj/linux_x86_64_gfortran--serial" ARCH=linux_x86_64_gfortran--serial castep
make[1]: Entering directory '/root/CASTEP-20.11/obj/linux_x86_64_gfortran--serial'
