# To subscribers of the xforms list from =?ISO-8859-1?Q?Nicolas_Castagn=E9?= <nicolas.castagne@imag.fr> :
Hi Eddie,
i do not have the time now to give a close look to your gdb backtrace.
However...
Note that XForms and X11 are not 'thread safe', in the sense you should
not perform calls to the XForms or X11 libs from different threads. The
graphic calls and event handling should be performed in a single
thread. Threads sould be used only to manage the core of your
application (such as computing datas, handling files, etc.).
In addition, note :
1) that since OpenGL is somehow thread-safe, you may manage GL objects
from different threads (provided you are carreful). You may find
various "threads" cocnerning that point in the list archive
http://bob.usuhs.mil/mailserv/list-archives/ .
2) that most GUI toolkits you may use have the same 'problem', as far
as I know.
Wish it could help !
Nicolas
