I had the same problem and traced it to the same source as you.
mod_jk.c
s->remote_host = (char *)ap_get_remote_host(r->connection,
r->per_dir_config,
REMOTE_HOST);
Requests worked fine until I did a request with query parameters.
In that case Apache logged "child pid 18323 exit signal Bus Error (10)".
The only difference I found was that if r->per_dir_config was NULL it
worked.
The only case were this member variable was NOT null was with requests that
had query parameters. Don't ask me why.
I changed the line in mod_jk.c to ...
s->remote_host = (char *)ap_get_remote_host(r->connection,
NULL, REMOTE_HOST);
... and it works now.
That's the only solution I could come up with, since there seem to be
only a small number of people that encountered this problem.

Going back to mod_jk version from tomcat_404 worked. I would like to use
the JK_1_2_0 version though, so if anyone could help debug it would be
great.
I am running on RH 7.2 install.
