Not sure if related, but Jürgen fixed an issue that had symptoms of a memory leak (although not technically a memory leak): https://www.mail-archive.com/search?l=mid&q=8ac50164fc1b3a3e7b249d2376555c58c37c9209.camel%40lyx.org From what I understand, the fixes should be in 2.5.0, so perhaps the above is not related at all. But it's possible further similar fixes are needed. Scott
