The only time I have seen it crash in that particular spot it was caused by another Apache module, I thought mod_ssl, but could be one of the LDAP modules. The other module was adding to the req.subprocess_env table in Apache, which is what that function is processing, an entry where the value was NULL rather than an empty string. This would cause Apache to crash. I'll have a quick look to see if can find old email but may be hard to find. As such, only recommendation can suggest is to update Apache first and see if it goes away.
