NSPR4.1.2/NSS3.3.3 versus NSPR4.7/NSS3.12

Hi All,

I have an SSL server application and an SSL client on an Windows XP machine.

The SSL server application seems to work perfectly in NSPR4.1.2/NSS3.3.2 but 
crashes in NSPR4.7/NSS3.12(I did a build using MozillaBuild).

Below is the crash stack trace.
ssl3_SendApplicationData(sslSocketStr * 0x01328be8, const unsigned char * 
0x01e5b08c, int 232, int 0) line 2094 + 49 bytes
ssl_SecureSend(sslSocketStr * 0x01328be8, const unsigned char * 0x01e5b08c, 
int 232, int 0) line 1180 + 22 bytes
ssl_SecureWrite(sslSocketStr * 0x01328be8, const unsigned char * 0x01e5b08c, 
int 232) line 1197 + 19 bytes
ssl_Write(PRFileDesc * 0x0131d128, const void * 0x01e5b08c, int 232) line 
1487 + 21 bytes
PR_Write(PRFileDesc * 0x0131d128, const void * 0x01e5b08c, int 232) line 146 
+ 20 bytes
ssl_send(void * 0x0131d128, char * 0x01e5b08c, unsigned long 232) line 171 + 
20 bytes

In the server application we have 2 listening servers on 2 different ports. 
These are initialized from 2 different code paths.
So NSS_Init is called twice. But this doesnt seem to cause a problem on 
NSPR4.1.2/NSS3.3.3. So I am wondering how this can be a problem with the 
server when running with NSPR4.7/NSS3.12

I even tried with NSPR4.6.4/NSS3.11.4 but i still get a crash.

Has anybody encountered a problem like this??

Thanks,
VT
