The problem with the segmentation fault has to do with the virtual host
support in Apache 2.2.
I'm using Ubuntu 12.04 with Apache 2.2 MPM Prefork. The way Ubuntu
suggests to set up the configuration is to have only general info in the
main conf file( apache2.conf) and always have the first virtual host as
the catcher for all other virtual hosts if any. So I put the oorexx
configuration directives in that (default) virtual host configuration.
When the time comes for mod_oorexx to set up the rexx interface,
oorexx_child_init
in handlers.cpp only looks at the first server_rec, which is the one
for general info, that is not invoked when a rex script has to be
invoked. By surrounding the setup with a loop to follow the chain of
(virtual) servers the setup will work for all of the servers.
i.e.
for ( ;s ; s=s->next) {
.... existing setup code
}
