There was no rev 189101 in cxx-conversion.  That is a trunk revision. 
In that range of revisions, there are only merges from trunk until rev 
188129, which introduces the new hash table.

Prior to that, we have rev 188059, which makes cosmetic changes to 
configure.ac.

If it's related to the hash table, then comparing rev 188059 vs rev 
188129 may show the regression.
