Was wondering what excatly is there in this segment? Does it have any information about the file descriptors /open file table ? I have a code which tries to override this segment but once I override this the program gets corrupted. Also why IPF kernel differs from other systems where the mmap space is below &_etext where as on other systems its above &_end. ?? Looking forward to hear from you. Best, Vamsi
