Gource crashes with --user-image-dir .git/avatar/

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Compile gource: $ CC=gcc-mp-4.8 CXX=g++-mp-4.8 ./configure
2. Build and install: $ make & make install
3. Change to git repo and run it: gource --user-image-dir .git/avatar/

What is the expected output? What do you see instead?

* The application running and display the user pictures.

* gource(70665,0x7fff71503960) malloc: *** error for object 0x10de6e820: 
pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
[2]    70665 abort      gource --user-image-dir .git/avatar/

What version of the product are you using? On what operating system?

OS: OSX 10.7.5

GCC: gcc-mp-4.8 (from MacPorts)

CXX: g++-mp-4.8 (from MacPorts)

Gource Versions: 
* 4.0 
(https://code.google.com/p/gource/downloads/detail?name=gource-0.40.tar.gz&can=2
&q=)
* 4.1 (https://github.com/acaudwell/Gource.git)

Please provide any additional information below.

I tried it first with the version from MacPorts which works with the 
--user-image-dir option very well. Unfortunately this was version 0.39 without 
the caption support.

Hi,

Sorry to hear it's not working.

Could you run try running it under gdb or valgrind to see where about in the 
code it is failing? eg:

gdb ./gource
run --user-image-dir /path/to/your/repo/.git/avatar/

Also do any of the image filenames have non-ascii characters? (Might be 
relevant).

Cheers

Andrew

Hi,

in the avatar folder were filenames with umlauts. I tried it with another 
folder with just one plain filename but the same error occurs.

Here is the output of the gdb:
run --user-image-dir /path/to/your/repo/.git/avatar /path/to/your/repo/
Starting program: /path/to/gource-0.40/gource --user-image-dir 
/path/to/your/repo/.git/avatar /path/to/your/repo/
Reading symbols for shared libraries . done
gource(72496,0x7fff71503960) malloc: *** error for object 0x100411820: pointer 
being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

Program received signal SIGABRT, Aborted.
0x00007fff84bb0ce2 in __pthread_kill ()

I am not sure if this will help you.

Just a guess, but it might be that you have some C++-based libs (eg boost 
system/filesystem) that were built with a different version of GCC (eg if they 
were built for the Xcode 4.2 GCC), as C++ libs tend to break between compiler 
versions:

ing-fail

Since the user image loading code now uses boost filesystem it might be this.
