AngelScript stack misaligned causes SIGSEGV on SSE-optimized libraries

[erolm-a]

Hi there,

It seems AngelScript causes some issues in modern Linux distributions (e.g. Arch Linux) that optimize some libraries like Mesa and libogg. However, as AngelScript misaligns the stack (the __stdcall attribute on GCC and Clang is usually ignored) when a SSE instruction is executed and a memory operand is not 16 byte aligned, a CPU exception occurs.

To fix this, you just need to recompile AngelScript with the "AS_MAX_PORTABILITY" macro turned on.

Somebody on the forum compiled such library with the flag turned on, see https://www.frictionalgames.com/forum/thread-56758.html . Could you please update your dependency zip?

A bit of foreword: your Steam builds for ALL penumbra games are broken for this reason on a number of target machines (Arch Linux, Ubuntu, Fedora, ... any distro that enables optimizations on final package builds). Apparently GOG builds too. I could only complete Overture with my build. I tried to reach out to you in many ways, but so far received no reply from any dev. We, Penumbra players who paid this title on steam, need some assistance. I understand the game is fairly old and this repo has not been updated for 6 years despite there are some pending PRs out there that should at least be discussed. Especially when they are so simple.
