[microblaze-uclinux] PPPD problem with fork()

[sgomes@xxxxxxxxxxx]

Hi,

I currently use the petalinux system
with MMU support. I use the sources files retrieved from petalinux-mmu-v0.10.tar.gz
and not the latest sources files.
When I try to use pppd application to
communicate with a modem, I have a bug.
I use pppd with the connect option
which gives pppd a command to execute. This command is executed using a
fork() and execv().
The problem is that after the fork()
call, in the created child, the pointers, pointing on strings in the parent,
point on a NULL pointer.

But if I compile pppd with #define
__uCLinux__  which implies to use a vfork() instead a fork(),
pppd runs properly.

Has someone met the same problem in
pppd or in other applications using a fork()?
