A couple of buildfarm animals, eg [1], are mildly unhappy:

In file included from ../../../src/include/nodes/execnodes.h:37:0,
                 from ../../../src/include/catalog/indexing.h:19,
                 from attribute_stats.c:21:

  if (SOFT_ERROR_OCCURRED(&escontext))
      ^

I think what we've done in other places is just to test
escontext.error_occurred directly, since the rest of the
macro is useless in this situation.
