http-redirect url gets corrupted in request_rec - apache 2

[SAILESH KRISHNAMURTI, BLOOMBERG/ 731 LEXIN]

Hi, i have an authentication module that i am trying to port from 64 bit 
linux to 32 bit solaris. 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?
