When closing a search tab (apparently GTK+ issue)
« on: October 02, 2008, 12:35:49 AM »
Closing a search tab. It looks to me like a GTK+ bug (!)

I will produce it with debug symbols, if possible.

OK, I will compile aMule with debug code (and debug symbols) and post a backtrace created with gdb.

(Will that be enough?)

Yet another crash, but this seems related to something else.

All these crashes are happening only with the non-debug version  >:(

I think I have reported 2 different issues here (where's the issue tracker?).

1) the first issue is happening when closing a search tab. I can successfully reproduce it when opening two search tabs, download something from the 2nd and then close all tabs. Upon closing the first tab, aMule will crash (both with debug and non-debug version). More details will follow as soon as I get a full backtrace.

2) the second issue happens randomly and maybe similar to iz0bbz's problem.

I am now recompiling the whole lot with MULECFLAGS += -fasynchronous-unwind-tables

Opened two search tabs, downloaded something, closed them both, crash upon clicking 'X' of the first and last search tab.

I am now recompiling the whole lot with MULECFLAGS += -fasynchronous-unwind-tables

I wasn't clear, you should ensure "-fasynchronous-unwind-tables" is NOT present in compilations options.  And try switching from "-O2" to "-O0" .
Ok, I modified that now. Recompiling...

Other issue, in your last backtrace there is  no debug information at all, and it is quite useless to developers. Did you follow wiki instructions on creating useful backtraces ?

Yes, but I don't know why no debug symbols where present. I am using this command line:
Code: [Select]
./configure --with-wxshared --disable-upnp --with-languages=it,en_GB --disable-optimize --enable-debug

I loaded the executable with gdb and ran the backtrace commands.
I will create another backtrace...

The --disable-optimize parameter (given to configure) seems to workaround this bug!

I don't know how it modifies the make process, but the resuling executable is no more affected...I will now try a non-debug version also configured with --disable-optimize

--enable-optimize only adds -O2 to the compiler flags. The only change when you disable it is that -O2 won't be added. Seems like your compiler does something wrong with optimization.

Gee..looks like I was right.

I am now testing the GTK+ patch, thanks for the pointer!
