/* A map from TEMPLATE_DECLs that we've determined to be erroneous
   at parse time to the location of the first error within.  */

erroneous_templates_t *erroneous_templates;



cp-tree.h:extern erroneous_templates_t *erroneous_templates;



Hmm, no GTY marker in either definition and since it could contain GC memory
and across ggc_collect, I suspect it needs one.

This was added with r15-2774-g596d1ed9d40b10 .
