Hi Everyone,
I tried on two different occasions to enter this bug on the gdb bug
entry page, and both times the process failed -- I submitted, but no
PR was generated. So I'm posting the details here.
AN EXECUTABLE FILE IS AVAILABLE TO REPRODUCE THE ISSUE -- I didn't
attach it because many mail lists reject attached documents.
Environment:
Linux Fedora Core 4, 2.6.12-1398
i686
GDB 6.3
KDbg 1.3 or 2.0 (doesn't matter)
Issue:
Open Kdbg; select an executable to debug.
Error message: "'gdb' exited unexpectedly"
This issue happens for a binary compiled with gcc 4.0.1 as well as one
compiled with gcc 3.3.
I have contacted the Kdbg folks, and they have investigated and assure
the issue is with GDB. Other KDE users are experiencing this issue.

As I told you, it was filed but the outgoing mail was lost. It's PR
2019. The mail problem has been fixed. However, the PR has absolutely
no information useful for anyone to reproduce anything. Neither does
this message. Presumably "the kdbg folks" know something more specific
about what the bug is; why don't you include _that_ information?
How about when loading your executable directly into GDB? Does that
work?

Can someone add my test program (clipview) to the PR 2019? I can email
it directly to someone....
The program works when debugged from the command line as follows:
gdb clipview
r
Here is the instructions someone was given from the kdbg people who
were trying to debug this, which I followed -- this is basically the
commands issued by Kdbg, as copied from a log of launching with Kdbg:
gdb
set editing off
set confirm off
set print static-members off
set print asm-demangle on
define kdbg__alllocals
info locals
info args
end
set prompt (kdbg)
file "clipview"
set args
info breakpoints
info line main
At the "info line main" point I got:
Segmentation fault

The binary you send me does not crash at this point in any version of
GDB I tried. Have you build GDB CVS or 6.3 from source to try, rather
than using the preinstalled packages on your system?

Did you follow the series of commands below, or just go:
gdb clipview
Because the latter works -- it is the sequence below that fails, and
that is the sequence emitted by Kdbg when it loads an executable.

Yes, I followed your example.

Rebuilding gdb 6.3 seems to have eliminated the problem! Thanks!

Thanks. In that case, you may want to check for GDB updates from
Fedora, or report the bug to them.
