From 7878653e8dbd65d94ea8ea8bae6e0afd3c3d0af3 Mon Sep 17 00:00:00 2001 From: Amlal El Mahrouss Date: Tue, 27 May 2025 23:02:19 +0200 Subject: fix: fix SEGFAULT on CxxDrv (AMD64), caused by a stack corruption. refactor: Refactor LibCompiler's codebase, deperecate older C compilers, and fully focusing on C++ now.
