Hi Ivan,

I compiled gnustep-base for Android using your code from 
I picked up your helloJni Application from 
http://ivan.vucica.net/public/android-objc/Android%20Obj-C.pdf   and modified 
provideString to call NSDate instead of returning an static string. FYI 
hello-jni.m was compiled as part of gnustep-base itself.

This is how my provideString function looks (ignore useless variable tmp)


    NSDate *date = [NSDate date]; 
    //return "This is from provideString function";
    char *tmp = malloc(1024*sizeof(char));
    return tmp;

When I execute helloJni on an Android phone application crash in 
NSPathUtilities.m. Using the crash dump I found that application crash at a 
line where geteuid is being invoked.

Function: NSString * NSUserName(void)

Line:  int uid = geteuid();
Called From

Function:  - (id) init
Line : return [self initWithUser: NSUserName()]; 

Can you please give me some pointer on possible cause of this issue?
