Hello,
I registered with the Source Forge (user name: steve_wood), but I could not
get anywhere from the login page. I kept getting an error (words to the
effect) "error in secure channel".
The reason I wanted to register is to report a bug. So, if you don't mind,
I would like to report this bug using this e-mail. PLEASE LET ME KNOW if
you cannot forward this to the appropriate party.
The following error message is printed on stderr when executing the
"XmManageChild(dialog)" command:
X Error of failed request: BadValue (integer parameter out of range for
operation)
Major opcode of failed request: 12 (X_ConfigureWindow)
Value in failed request: 0x0
Serial number of failed request: 197
Current serial number in output stream: 198
The code sequence that generated this error is from the sample code
provided for Volume Six A: Motif Programming Manual (Oreilly & Associates
Inc). The actual program is "hello_dialog.c" (Dan Heller and Paula
Ferguson Copyright 1994) and is enclosed below.
The actual fragment that causes this error is:
.
.
.
/* Create the InformationDialog as child of button */
dialog = XmCreateInformationDialog (button, "info", args, n);
/* no longer need the compound string, free it */
XmStringFree (xm_string);
/* add the callback routine */
XtAddCallback (dialog, XmNokCallback, activate, NULL);
/* manage the dialog */
XtManageChild (dialog);
(at which point it crashes and produces the above mentioned message)
I compiled and ran this program (unmodified) on a NEC Versa LX running
Redhat Linux 7.0 using the gcc compiler. I have never had any problems
with Linux. Motif, or gcc up until now. The motif library is actually
LessTif, installed from the binary 91.4-1.i386 rpm's. I get the same error
using the Motif 1.2 or 2.0 widgets.
I ran the program using gdb "run -sync" and it crumped at the same place
with the same message. I added a break point just before the call to
XtManageChild and did a stack trace. The results are included below in
gdb_output.txt.
I would appreciate any advice on how this problem can be overcome.
Sincerely,
Steve Wood
