Steps to Reproduce

Installing rocm from therock repo, pip freeze:

rocm==7.11.0a20260111
rocm-sdk-core==7.11.0a20260111
rocm-sdk-devel==7.11.0a20260111
rocm-sdk-libraries-gfx110X-all==7.11.0a20260111

Executing amdflang -c -o test.o test.f90 on

program test_nested_alloc
    implicit none
  	type :: nested_t
		integer, allocatable	:: pa(:)
	end type


    type (nested_t), allocatable :: tmp_data(:)

    allocate (tmp_data(1000))

end program test_nested_alloc

test.f90 compiles successfully with amdflang from the latest ROCm 7.2.0 release installed via quick-start here, so the fix should show up in future TheRock nightlies once the compiler submodule is bumped. Thanks for your patience!
