Sure! my pl_gram.c generated by this version of bison is :
403 typedef union
404 #line 115 "gram.y"
405 {
406 core_YYSTYPE core_yystype;
.........
454 PLpgSQL_case_when *casewhen;
455 }
456 /* Line 193 of yacc.c. */
457 #line 458 "pl_gram.c"
458 YYSTYPE;
and cause the generated pl_gram.c problematic.
