+       The regs_allocated field in a struct re_pattern_buffer refers
+       to the state of a particular re_registers struct when used in
+       successive matches using the same compiled pattern.  Avoid a
+       SEGV in `renamesyms' resulting from using a new re_registers
+       with an existing re_pattern_buffer:
+
+       * modules/gnu.c (m4_pattern_buffer): Wrapper struct for associated
+       pattern buffer and registers.
+       (m4_regexp_search): New function to call re_regexp_search with
+       correctly matched pattern buffer and register instantiations.
+       (m4_regexp_compile): Return an m4_pattern_buffer.  Adust all
+       callers.
