Segmentation fault with LookupTables

[StevenD57]

I have a MS1 v2.2 unit and it has MSExtra 029y4 code loaded. I am running MegaTunix 0.9.22 and when I go into Tools -> MS Lookuptables to select any of the different WBO2 lookup tables packaged with MegaTunix, the program segfaults and dumps a back trace.

My steps to reproduce are:

turn on power to MS1 unit
fire up MegaTunix
go to Tools -> MS1 Lookuptables
double click on WBO2 table value
pull down menu to select AEMWB or TEWB or anything other than default
click on any of the other lookup table selections
BANG! segfault

Do you want the back trace file it generated?


it outputed 10 - 15 messages about:

(megatunix:7969): libglade-WARNING **: unknown property 'always_show_image' for class 'GtkImageMenuItem'

and then it says:

*** glibc detected *** megatunix: double free or corruption (out) 0x0000000000ee8d00 ***

and then it generated a backtrace and memory map.

Can you try with a Git checkout and see if the bug is there?

See the http://www.msextra.com/forums/viewtopic ... 06&t=23548 thread and scroll down to the "Downloading and compiling MegaTunix from Git" section

Even worse. Just after interrogating the ECU that one died.

Without debugging enabled (configure --enable-debug) and running with "--g-fatal-warnings" under GDB, the traces are pretty useless.

So to summarize
recompile with debugging
./configure --enable-debug ; make clean ; make ; sudo make install
cd src
gdb ./megatunix
run --g-fatal-warnings

then send the output.

I have duplicated and fixed these issues and pushed the fixes into the main Git repository.

Please pull and retest
i.e.

Code: Select all

cd git/MegaTunix
git pull
./autogen --enable-debug ; make clean ; make ; sudo make install

[StevenD57]

Yes, that seems to work on both counts. I can now select other LookupTables as well.
I will continue to test and let you know if I have any issues. Thanks for the help.

Lots of updates went in today, so lemme know of things that may come up (same git pull ; ./autogen.sh ; make ; sudo make install) ...

Unfortunately my MS1 box seems to have bit the dust this past weekend so I will have to wait until I get it back from Peter Florance at PFTuning before I can do any more testing.
