/* gpu_v2_bad.c - ABI-breaking v2 but keeps the v1 SONAME.
 * THIS IS THE BUG: a library author ships a layout change but
 * doesn't bump the SONAME major version.
 *
 * Build: gcc -shared -fPIC -Wl,-soname,libgpu.so.1 -o libgpu.so.1.1.0 gpu_v2_bad.c
 * Then:  ln -sf libgpu.so.1.1.0 libgpu.so.1   (replaces the old v1 symlink)
 *        ln -sf libgpu.so.1     libgpu.so
