I just wanted to point out that the recent change to glist_delete() (commit herehttp://pure-data.git.sourceforge.net/git/gitweb.cgi?p=pure-data/pure-data;a=blobdiff;f=src/g_graph.c;h=cdebbdc981bb35b24d55baaf4c401254b4c65aea;hp=57db6556efe9f60777f15b9d2e9d8f0c627c4aa0;hb=5c78db0883a3450e1cac727aee422ad7f4dd56eb;hpb=c7fb8e4a06d6253890ca2f73dfe4980c8c88fce9) is causing crashes in libpd when closing patches. Not sure if it is actually related, but it seems pretty similar to the bug already submitted herehttp://sourceforge.net/tracker/?func=detail&atid=478070&aid=3433140&group_id=55736, which appeared a few days after the commit that I linked to. I'll place the backtrace here, indicating that there is a stale pointer that is being accessed somewhere (this is on an EXC_BAD_ACCESS):
