Description Chris Evans 1999-06-14 19:13:47 UTC

Hi

I have a program I build on a Redhat5/glibc2.0/g++-2.7.2
combination. This program is written in c++. It worked fine
on RH5.2

On RH6.0 it is completely broken. The fread() in the
compatibility library looks hosed.

If I do ltrace and strace I see

1) Old binary calls fread().
2) fread() is entered in, I believe, the libg++
compatability library
3) The stupid library calls the write() system call!!

You are welcome to the binary that causes this. It is a BBC
emulator.

To reproduce I would try a simple program that uses c++ and
calls fread(), build it on RH5/glibc2.0/g++-2.7.2, and see
if the binary works on RH6.0.

Sadly I have no access to such a machine. If anyone reads
this and has such a machine, and wants to help, mail me.

Chris
