rdstate() is dumping core on Linux 2.6.x kernel

[lkpaturi]

Hi,

I build my executable on a 2.4.x kernel and was running as expected on the same system. Where as when I tried to run it on 2.6.x kernel it was dumping core and the stack trace shows rdstate()

My code check the stream status before calling socket read() function. I'm using

ios *x;

if((x->rdstate() & ios::badbit) != 0)
{
return 0;
}
else
{
....
...
sock->read(...)
..
..
}


When I observed there is diff in rdstate() output on 2.4.x & 2.6.x linux servers


On 2.6.x kernel
ios --> rdstate():0 badbit:4 failbit:2 eofbit:1 ==> for good conditon

ios --> rdstate():192 badbit:4 failbit:2 eofbit:1 ==> for bad condition


On 2.4.x kernel
ios --> rdstate():172 badbit:4 failbit:2 eofbit:1 ==> for good condition

ios --> rdstate():14 badbit:4 failbit:2 eofbit:1 ==> for bad condition





I'd like to know whey rdstate() is returning diff values for diff kernels. Any help would be greatly appreciated
