Ok, I installed Win7 in a virtualbox, got Lazarus, installed the 
"JetBrains mono" font (just the regular, skipped all the 
light/italics....) and "JetBrains mono Variable".

No crash.
Ligatures work (well the subset as described in other mail)

Without any way of reproducing, there isn't much I can do.

Can you try to catch it in the debugger, and see what params are given 
to NewTextOut
in
#2  0x00ab95f6 in DRAWHILIGHTMARKUPTOKEN (ATOKENINFO=..., 
parentfp=0x13abf6e8)
     at lazsyntextarea.pp:1741

  fTextDrawer.NewTextOut(TxtLeft, rcToken.Top, TxtFlags, tok, 
ATokenInfo.Tk.TokenStart, ATokenInfo.Tk.TokenLength, FEtoBuf);
