I've been porting a Lua/IUP application written for Windows and Linux to
Solaris 5.8. I puzzled for quite a long time over the fact that the
program crashed (with a segmentation violation) shortly after the window
started to be drawn. Eventually I tracked the problem down to the use of
the newline character '\n' in a button title. I find that a similar crash
will occur if '\n' is used in a tab's TABTITLE attribute. With the newline
character removed. both button and tab control work as expected.
My environment is Solaris 5.8, Motif 2.1.0, and IUP 3.6 built from recent
CVS sources.
If this is an inherent limitation of the old Solaris or Motif version, it
would probably be good to document the exception; the description of the
button TITLE attribute presently says "The '\n' character is accepted for
line change", and the description of the generic TITLE attribute says "The
'\n' character usually is accepted..."
