From 80b5886884ac6da7266a89cfb42a88a272110e31 Mon Sep 17 00:00:00 2001 From: Kevin Lenzo Date: Fri, 12 Dec 2025 10:12:41 -0500 Subject: [PATCH 01/10] Fix undefined behavior and add bounds checking in phone compaction Prevents strcpy with overlapping memory when i==j (undefined behavior). Adds bounds check before array access to prevent buffer overflows.

Removed libfst-dev and libngram-dev from default install steps - Disabled BUILD_G2P by default (it already defaults to OFF in CMake) - Only train-g2p-lda-vtln job uses ubuntu-22.04 and installs G2P deps - G2P job rebuilds sphinxtrain with -DBUILD_G2P=ON - All other jobs run on ubuntu-latest without optional dependencies This makes G2P truly optional and allows CI to work on any Ubuntu version. --- .github/workflows/tests.yml | 37 ++++++++++++++++++++----------------- 1 file changed, 20 insertions(+), 17 deletions(-) diff --git a/.github/workflows/tests.yml b/.github/workflows/tests.yml index 40083cc7..ecd94b50 100644 --- a/.github/workflows/tests.yml +++ b/.github/workflows/tests.yml @@ -4,7 +4,7 @@ on: -
