(In reply to comment #2) > > Which version do we talk about? > > 3.21.38 Ok. Thanks. The problem is I can not reproduce the bug. Your gdb outputs (thanks, was helpful) showed that the segmentation fault was within fltk's set_fonts routine. As that routine is called from fldigi with correct parameters there may be one of the following reasons: 1. fltk-1.3 misses USE="xft threads" 2. Something on your fontinstall is broken (you have to have some ISO8859-1 fonts installed) 3. Your .fltk directory got borked somehow (should be ok to delete that directory for a quick test). Please check your settings and report back.

(I apologize. I know there are better ways to present this but am not really familiar. Hope I get points for trying! :) ) In fl_set_fonts_xft.cxx, function make_raw_name(...) it appears there is the possibility of dereferencing a NULL pointer (*style) ? when I change FROM: 93 char *style = strchr(pretty, ':'); 94 char *last = style + strlen(style) - 2; 95 96 if (style) 97 { 98 *style = 0; // Terminate "name" string 99 style ++; // point to start of style section 100 } TO: 93 char *style = strchr(pretty, ':'); -> 94 char *last ; 95 96 if (style) 97 { -> 98 last = style + strlen(style) - 2; 99 *style = 0; // Terminate "name" string 100 style ++; // point to start of style section 101 } The auto-config wizard dialog opened. It looked fine, but thats as far as I am getting tonight. Hope it helps. Let me know if you would like me to try something else. Also, my system is configured for a default locale of en_US.UTF-8. Is that possibly related?

That would be a possible bug in fltk-1.3. But why do only You observe that. Please run the unmodified code under gdb until it crashes. After the segfault you should be able to 'p pretty' (or 'p *pretty') to see what make_raw_name get as parameter. Your bug happens if no ':' is in the pretty font name. > > Also, my system is configured for a default locale of en_US.UTF-8. Is that > possibly related? No that is well.

So, I added a printf("%s,%s\n",raw,pretty) to the start of make_raw_name(). The last few lines before the crash are: BNimbusSanTExt,Notes:style=Normal Notes,OCR\-A:style=.egular OCR\-A,OCRAM:style=.egular OCRAM,OCRATTRegular:style=.egular OCRATTRegular,OCRBLetM:style=.egular OCRBLetM,Odessa LET:style=Plain Odessa LET,OkayD:style=.egular OkayD,Old English Gothic So, fltk is choking on the "Old English Gothic" font.

(In reply to comment #6) > So, fltk is choking on the "Old English Gothic" font. The font is usable in > OpenOffice at least. OK, thanks for the good work. Can you please look which package installs this font. I would like to try it myself, but need to find that font first. For the fldigi problem: There is nothing we can do from this side. You can only deinstall the font for the moment and we will need to open a bug for fltk to fix the bad coding.

Can you please look which package installs > this font. I would like to try it myself, but need to find that font first. The font file is not claimed by any package. I think it came from a "2000 Truetype Fonts" CD that I bought years ago. I checked all the other entries from the fc-list output. This "Old English Gothic" font is the sole font that does not have a "style:" attribute, so it seems badly done! Still, I suppose a malformed font should not break fltk. If you need to duplicate the behavior, perhaps you could edit a temporary copy of a font with fontforge or something like that, removing any "style:" entries? > For the fldigi problem: There is nothing we can do from this side.

Thanks very much for helping me track this down.
Potential problem is fixed in fltk-1.3.2_p10088. so the bug can be closed as soon as that package goes stable.
(In reply to Thomas Beierlein from comment #9) > Potential problem is fixed in fltk-1.3.2_p10088. so the bug can be closed as > soon as that package goes stable. With ftlk-1.3.3-r2 coming stable the bug can be closed now.
