Re: need to read (to debug) zsh.core

[Valery Kobrin]

Sorry, I was not enough precise.
`file zsh.core` says: zsh.core: OpenBSD/i386 core from 'zsh'.
zsh version 4.0.4, build from OpenBSD package zsh-4.0.4.tgz with the
pkg_add command which does everything automatically, not allowing to
make modifications, like: "configure --enable-zsh-debug".

You are right, gdb reads zsh.core somehow, but I could not extract from
it any useful information, like the line, on which the script crashed.
And gdb does not allow to debug zsh script.

So, now my question is: is there some way to debug large zsh script
like "C" or "C++" program?

Thanks,
Valery

The core files should be readable by gdb or dbx.  However, by default
zsh is compiled using optimization and with debugging symbols stripped,
so there won't be very much useful information in the core file unless
you built zsh with "configure --enable-zsh-debug".

What does `file zsh.core` say?

Yup, rename it to 'core' and try again.

You can use its file dialog to open the core file.

I'm sorry, I'm not so good with this, in order to understand what it'll
give me, if I rename it (what? zsh.core file?).
As to DDD, as I know, it is not more than graphical interface for the
real debuggers, so it cannot help much?...

Did you try to rename it? Did you try DDD?

need to read (to debug) zsh.core

[Valery Kobrin]

Hi zsh gurus,

I need to debug zsh crashes, which leave zsh.core, but gdb and dbx
don't understand it. I hope there is some way to use zsh.core,
otherwise - what for it would be dumped. Let me, please, what way
it is.

Thanks,
Valery
