[LAD] Aeolus 0.9.0 backtrace

I rebuilt aeolus again agains of debuggable clxclient, now backtrace is a bit more full. Before i got it i added debug printing lines with args, and printing internals of some structs. However, Display struct seems to be not for user, and its structure is quite huge, including other structs as well. int X_textip::textwidth (int i, int n) { printf ("DEBUG: entered textwidth: %i, %i\n", i, n); XGlyphInfo K; if (n == 0) return 0; printf ("DEBUG: predicting XftTextExtentsUtf8 args: Display * dpy (see DPY section), %p (see FONT section), %s, %i, &K\n",_style->font, (const char *) (_txt + i), n); Display * DPY = dpy (); XftFont * FONT = _style->font; printf ("DEBUG: FONT (struct XftFont):\n"); printf ("\tascent (i): %i\n", FONT->ascent); printf ("\tdescent (i): %i\n", FONT->descent); printf ("\theight (i): %i\n", FONT->height); printf ("\tmax_advance_width (i): %i\n", FONT->max_advance_width); printf ("\tcharset (FcCharSet *): %p\n", FONT->charset); printf ("\tpattern (FcPattern *): %p\n", FONT->pattern); printf ("DEBUG: DPY (Display): %p\n", DPY); XftTextExtentsUtf8 (dpy (), _style->font, (const FcChar8 *)(_txt + i), n, &K); return K.xOff; } (gdb) run Starting program: /home/nick87720z/Рабочий стол/aeolus-0.9.0/source/aeolus -J warning: no loadable sections found in added symbol-file system-supplied DSO at 0x7ffff7ffa000 [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
