Binutils experienced a segmentation fault in the image_write_section function specifically for vms-alpha targets, triggered by malformed object files created through fuzzing. The root cause was a missing null check for image_section. This commit adds the necessary check, preventing crashes when image_section is null and thus improving the robustness of the vms-alpha object file handling against corrupted inputs.
