morandidodo at gmail dot com changed: What |Removed |Added ---------------------------------------------------------------------------- Known to work| |6.2.1 Known to fail| |5.2.0 --- Comment #2 from morandidodo at gmail dot com --- I am sorry, but it has been more than an year and now I am using GCC 6.2.1, I am not able to reproduce the bug anymore. Indeed, the new version seems to work flawlessly, and I do not get segfaults even with the address sanitizer. If someone have the 5.x branch installed, the Voxelands commit which caused the problem was the fa519dee2751b46ee36f4443d5b194dbbe1dd1e5. Otherwise, I could close the issue. I do not know if it is worth to track down strange and uncommon issues with an old version of the compiler...
