If it does work, would you please submit it as a patch for the next
release? At least, add a note that the font ligatures feature only
supports monospaced fonts and only works on Windows. It's better

revision 63951
Windows only, compile with -dWINDOWS_LIGATURE
Tested with Cascadia.
Lazarus hangs on start for me on Windows 7 when compiled with this
define.
Lazarus 2.1.0 r63957 FPC 3.2.0 i386-win32-win32/win64. I use JetBrains
Mono font.
Could you start with an empty project? To make sure its not content
related?
Though the code changes do not have any loop.
You could run in gdb
gdb lazarus.exe
r
ctrl-c when it hangs
bt
Tried with an empty project, nothing changed. Actually it does not hang,
it segfaults. GDB output:
