Ctrl+F crashed only when built with '--disable-deprecated'. If configure from normal way, there was no crash anymore: `./configure --program-suffix=131 --prefix=$PWD/0exe` I did not try your suggested debug ways due to limited spare time, sorry. System info: Debian 9, xfce4 4.12, configure log (same for with --disable-deprecated or not): ``` Install Geany in : /home/aa/tools/src/geany-1.31/0exe Using GTK version : 2.24.31 Enable binary relocation : no Build with plugin support : yes Use (UNIX domain) socket support : yes Use virtual terminal support : yes Build HTML documentation : no Build PDF documentation : no Build API documentation : no Generate GtkDoc header : yes ```
