When a network game starts, after the loading screen, the game freezes for a moment, then crashes.

The console output is similar to

$ megaglest
megaglest v3.13.0
Compiled using: GNUC: 140201 [64bit] platform: Linux-X64 endianness: little
GIT: [Rev: $5604.3a5d459$] - using STREFLOP [SSE] - [no-denormals]
Game unique identifier is: 06e55166-ee27-11ef-affe-fd95e2b16f6a
/usr/include/c++/14.2.1/bits/stl_vector.h:1130: std::vector<_Tp, _Alloc>::reference std::vector<_Tp, _Alloc>::operator [with _Tp = Glest::Game::NetworkCommand; _Alloc = std::allocatorGlest::Game::NetworkCommand; reference = Glest::Game::NetworkCommand&; size_type = long unsigned int]: Assertion '__n < this->size()' failed.

I got this output now when trying megaglest from the Manjaro package (on Manjaro). I cloned the MegaGlest Arch PKGBUILD repo and built with makepkg. I see by default MG is being built with -D_GLIBCXX_ASSERTIONS.

I noticed this when working on the meson PR (#256) and added the b_ndebug=true option:

    'buildtype=debugoptimized',
    'cpp_std=c++11',
    'b_ndebug=true',

which removes -D_GLIBCXX_ASSERTIONS from the build.

MegaGlest should work as expected whether that flag is added or not. This issue needs to be debugged and fixed.

I opened a separate issue on the Arch repo https://gitlab.archlinux.org/archlinux/packaging/packages/megaglest/-/issues/1

This the output when a network game starts, when MG is built with '-fsanitize=address,undefined' using gcc
