http-redirect url gets corrupted in request_rec - apache 2.2.0

[SAILESH KRISHNAMURTI, BLOOMBERG/ 731 LEXIN]

Hi, i have an authentication module that i am trying to port from 64 bit 
solaris to 32 bit. The problem is that when the module redirects the request to 
the authentication page, the URL seems to be getting corrupted when it is 
passed betwen the module and apache core.                                       
For E.G; Within the module request_rec->headers_out is /loginPage/Somelogin.cgi 
apache seems to actually redirect to:\xfb\xab\x98\xb0Page/Somelogin.cgi         
i dont know why this is getting corrupted. Tried logging various parts of the 
request_rec but didnt find anything. Does anyone have any ideas?
