| Fluid throws a segmentation fault when I try to create a new widget class while another widget class is already selected.
(Sorry - I opened this a few weeks ago but was then distracted by exams until now.)
I have played around with this some more and found that it only happens if the parent widget class is closed. So, to reproduce:
* Create a new widget class
* Close the widget window
* Create another widget class (with the original widget still highlighted)
For me this causes Fluid to crash on Ubuntu Linux and Solaris.
Can anyone else reproduce?
thanks | |

| Also, I don't actually want a sub widget class, but it was annoying that it crashed when I did this accidentally. | |

| Nothing was fixed in 1.1.x because we could no duplicate the crash.
There is actually new information in this that, according to the poster, makes the crash repeatable. I have tested it on MSWindows/VC6, but it does not crash. The OP uses Linux though. I will test Linux later when I get to the machine. | |

| I can confirm that following the above procedure does produce a segmentation fault. I'm running Debian Etch 4.0. | |

| And on Solaris as well. Same result:
bash-3.00$ ./fluid
Segmentation Fault (core dumped)
bash-3.00$ uname -a
SunOS leda 5.10 Generic_125100-04 sun4u sparc SUNW,Sun-Fire-V890
bash-3.00$
BTW, compiling on Solaris with gcc 3.4.3 results
in lots of the following warning:
warning: ignoring #pragma ident

| The sequence described would attempt to create a subwindow of a window that was unmapped. Fl_X::make_id would insist on the parents xid and crash. The fix marks the subwindow as visible, but doesn't actually create an X-Window. This should be done automatically when the parent window is mapped again via the FL_SHOW command.
I leave this bug active because even though I avoid the crash, mapping still does not work as expected. | |
