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);
Can you add some debugln in a format convenient to you? This will
simplify things, I think.
This is in the paint handler, and it is called for each token. So
potentially very slow with debugln.
But since it is in startup, hopefully you wont have to many.
Apply this patch please
With this patch applied Lazarus seems to crash on debugln in
lazsyntextarea.pp. Just in case, I tried to remove this particular
debugln, then it printed 'BEFORE' and nothing more.
