/* $Header: /cvsroot/lesstif/lesstif/test/Xm/pushbutton/test17.c,v 1.4 2001/05/15 14:26:56 amai Exp $ To: lesstif@hungry.com From: Silverman Bill Subject: Bug Report I first encountered this bug in lesstif 0.83. All of my tests and developed applications worked ok on lesstif 0.81 . When I tried to upgrade to 0.83, on my SPARC station running SunOS 4.1.4 3 with X11R5 (IntrinsicP.h revision and date 1.57 91/06/26), it crashed every program and test, immediately. I thought that I had a bad source, and having better things to do, decided to pick up a later version of lesstif after a while. I picked up lesstif-current (creation date 980816) a few days ago, rebuilt and installed it, and the problem was still there. According to your instructions, I am supplying a test program and a stack trace. I really need lesstif for the SunOS system, since several of our public machines are old SPARCs, still running SunOS. Thank you for your attention, William Silverman ------------------ stack trace ----------------------- Starting program: /tmp_mnt/home/bill/bill/TOOLS/sunos-motif-egs/ch02/hello Breakpoint 1, main (argc=1, argv=0xeffff85c) at hello.c:26 26 XtSetLanguageProc (NULL, NULL, NULL); (gdb) continue Continuing.
