I was chasing an issue in duplicate transaction handling in 4.8 (Ubuntu 22.04). Encountered a double free crash while running 4.12. This is triggered by importing the same QFX file twice (or two distinct files with duplicate transactions). Valgrind reported the following: ==1315253== Invalid free() / delete / delete[] / realloc()==1315253== at 0x484B27F: free (in /usr/libexec/valgrind/vgpreload_memcheck-amd64-linux.so)==1315253== by 0x6819CEF: gnc_import_exists_online_id (in /disk2/nbu/src/gnucash.git/build-4.12/lib/gnucash/libgnc-generic-import.so)==1315253== by 0x682426C: gnc_gen_trans_list_add_trans_with_ref_id (in /disk2/nbu/src/gnucash.git/build-4.12/lib/gnucash/libgnc-generic-import.so)==1315253== by 0x6824158: gnc_gen_trans_list_add_trans (in /disk2/nbu/src/gnucash.git/build-4.12/lib/gnucash/libgnc-generic-import.so)==1315253== by 0x11AEB20A: runMatcher (in /disk2/nbu/src/gnucash.git/build-4.12/lib/gnucash/libgncmod-ofx.so)==1315253== by 0x11AEB679: gnc_file_ofx_import_process_file (in /disk2/nbu/src/gnucash.git/build-4.12/lib/gnucash/libgncmod-ofx.so)==1315253== by 0x11AEB93A: gnc_file_ofx_import (in /disk2/nbu/src/gnucash.git/build-4.12/lib/gnucash/libgncmod-ofx.so)==1315253== by 0x11AEBCFB: gnc_plugin_ofx_cmd_import (in /disk2/nbu/src/gnucash.git/build-4.12/lib/gnucash/libgncmod-ofx.so)==1315253== by 0x5AB4D2E: g_closure_invoke (in /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0.7200.1)==1315253== by 0x5AD0B75: ???
