Can you reproduce the issue? If so please provide a simplified example and step-by-step instructions to reproduce.

And what version of kdevelop and gdb do you use?

Also please provide the CMakeCache.txt file from the project (if you're using cmake, otherwise make sure that you've built your app using -O0 -g3 flags).

On my program I can reproduce this every time. I`m sorry but I can`t show you all this program, because it is commercial project and I only one of developers.

There is GDB internals commands up to the place where variables appears:
gdb --interpreter=mi2 -quiet

Yes I compile with this flags. I use gdb 7.0.1-58.1 Suse build and KDevelop  3.9.98 (using KDevPlatform 0.9.98)

If you could send me a simple, reduced application that still has the issue we can fix the problem. You could create one by removing all irrelevant parts in the code.

please re-open when you've provided the necessary sample.

I have sent code of project on witch I had found this bug directly to Niko Sams mail, because it is a commercial code (I`m not allowed to public it here) and I can`t (don`t know how to) write simple public example.

Ok, i found the issue:
(gdb) -stack-list-locals --thread 1 --frame 0 --all-values
^error,msg="Cannot access memory at address 0x1c"

Getting the locals fails with this error until the std::map is initialized.

SVN commit 1105448 by nsams:

Don't let -stack-list-locals get all values as we don't use them.

Instead we use -var-create on every variable to get the values. It would
however make sense to use the values from -stack-list-locals for better performance.

As a side effect this fixes problems where -stack-list-locals failed with an error
that a pretty printer of a variable in the stack caused; like the uninitialized std::map
in the referenced bugreport.
BUG: 229862

 M  +1 -1      variablecontroller.cpp  


WebSVN link: http://websvn.kde.org/?view=rev&revision=1105448

Related upstream bug:
http://sourceware.org/bugzilla/show_bug.cgi?id=11407

Niko, I`m sorry but problem is still exist:
Now all local variables is shown in time, or they names is shown in time, but they actual values is shown as before.

2 Niko: you can reproduce it: just check what value have variable "elements" "element_size" and "n" in the list of local variables just after atoi[argv[x]] calls but before creating of the map variable (lines 37 - 41 of space_pairwise.cc). They must be equal to the corresponding arguments, but they aren`t.

I see the problem, but unfortunately we can't do anything about it - this problem has to be fixed upstream in gdb.

OK I understand.

One more: at line 41 I have debug popup hint for elemens and elem_size but I haven`t such popup on n variable is it a bug?

Please open a new bug for that one, and attach the console output with gdb debug area enabled - only the lines that appear when hovering the variable.

OK: https://bugs.kde.org/show_bug.cgi?id=231466
