Segmentation Fault when running on Manjaro with glibc 2.25-7

[recyclojunk]

Firstly to get it to compile I had to remove the -Werror flag and remove the space in
(pthread_t)NULL; on line 216.

When I compile:

Usage: ./compile.sh [i386]
Add the i386 option to compile for 32-bit (i386) architectures on a 64-bit machine
Using sdl-config.
Converting built-in images to XPM format with imagemagick's 'mogrify' tool...
Converting other built-in files to .h file format with the xxd tool...

done.
Now run the 3D File System Browser with ./3dfsb

When I run it however, I get a segmentation fault:

GRIDCELLSIZE: 2.946484|2.578106
Segmentation fault (core dumped)

Any ideas of what I might be able to try to get it to work?

[tomvanbraeckel]

Strange, I did not have compilation issues due to the space or the -Werror. I'm using glib version 2.48.2-0ubuntu1...

I'm not sure what causes the segfault. It seems to be listing the files in / so you could try another folder with just one or 2 files in it, to check whether it's related to one of the files or folders it encounters.

More debugging, like adding some printf's in the code after that GRIDCELLSIZE output statement or running it with gdb (more advanced) should show you where it's crashing. It's probably a buffer overflow but hard to say where exactly at this point.

In any case, thank you for testing and creating this issue!
