>From include/plugin-api.h:

  /* This is the prevailing definition of the symbol, with no
     references from regular objects.  It is only referenced from IR
     code, but the symbol is exported and may be referenced from
     a dynamic object (not seen at link time).  */
  LDPR_PREVAILING_DEF_IRONLY_EXP

It looks like it should be made dynamic since it is exported.
Do you have a stand-alone testcase for this?
