[gentoo-user] BUG in glibc????

[capsel]

Hi all,

I am writing some program... simple program and I've got some code:

                j=strcmp( "log", *(lines+i) );
                printf( "ble\n" );
                if( strcmp( "log", *(lines+i) ) == 0 )
                {
                        printf( "ble2\n" );

it is in for loop. "ble" and "ble2" are some texts for debuging purposes :)
So... when I run my program I can see three times "ble" and only two
times "ble2"...
after last "ble" there is:

*** glibc detected *** free(): invalid next size (normal): 0x0804c208 ***
Przerwane

is it a bug in glibc or in my code?

I added file with that loop.
"Przerwane" means interrupted/broken/stopped, it is polish locale (LC=pl_PL)
