kernel crash when running pppd with debug option

Hello,

I have compiled pppd and I have some problems with it.

It seems to work ok, but when I try to run it with the "debug" option it crashes the kernel after connection is established. I don't get any crash if I remove this option. This is quite annoying since I can't debug it properly ...

I have tried with the version from uClinux-dist (2.3.8) and with the version from buildroot (2.4.3 that I had to patch). Both crash the kernel, but with the 2.4.3 version I also get a kernel crash when I try to use a connect script that uses chat.

I thought this kind of software was really stable, does anybody have an idea of where the problem might come from ? For information, I first had a kernel crash with no warning because I forgot to activate the 'support for console on Nios UART' kernel option. I find it strange that such a software does no such check before running...

Thanks a lot,

Regrards,

    Hi hippo,

    thanks for the help. I don't get any error message before the crash, I just see that the console is down (no response to anything).

    I tried to increase the stack size to 256k, but I still get the same problem.

    Thanks again, I ll look further.

    Regards,
