Description Need Real Name 2001-08-24 12:06:37 EDT

From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.7-2smp i686)

Description of problem:
konquerer crashes in many circumstances,
bringing up the crash handler window.

I have not been able to determine exactly what
sequence of actions will cause it _not_ to crash
but some sequences do exist.

Version-Release number of selected component (if applicable):


How reproducible:
Sometimes

Steps to Reproduce:
1.click on the konqueror icon in the panel

or

1.type "konqueror" on the command line
2.click in the location field
	

Actual Results:  The crash handler came up, I clicked "close",
and the KDE window went away.

Expected Results:  The program should have allowed me to proceed
with normal operation.

Additional info:

If I run konquerer as a file manager by
clicking on the home directory button on the
panel, I have _sometimes_ managed to get it
out of the state in which it crashes, by
navigating with the sidebar and clicking on 
folders and such. I have not been able to
reproduce that scenario, however.

Created attachment 29935 [details]
traceback from konqueror (default locale = ja_JP.eucJP)

Comment 2 Martin Wilck 2001-09-07 13:51:06 EDT

I might add: kspread crashes when it is first opened (empty document), kword
hangs when
first opened (empty document). I am not a KDE user and have other duties here,
so this was just
a quick scan, but rather disastrous.

*** Bug 53521 has been marked as a duplicate of this bug. ***

Comment 4 Bernhard Rosenkraenzer 2001-09-11 05:13:44 EDT

This is almost certainly a compiler bug since it works everywhere else (even 
on other 64-bit arches: alpha, s390x).
Adding Cc.

Comment 5 Jakub Jelinek 2001-09-11 05:19:25 EDT

This needs to be retested when all of kde is rebuilt with gcc-2.96-98 and above.

Comment 6 Ben Levenson 2001-10-18 12:37:31 EDT

I rebuilt and reinstalled the following RPMS and still received a backtrace.
 kdeutils-2.2-3
 kdelibs-2.2-11
 kdebase-2.2-13
 kdeadmin-2.2-9
 kdelibs-sound-2.2-11

---------------------
FWIW, I also rebuilt the qt RPMS, but to no avail.
Konqueror will open web pages if I click on the desktop links. I can surf
as long as I use the mouse, but it segfaults as soon as I try to type something
in the address bar.
I have an strace (from konqueror --nocrashhandler if it is useful)

Comment 7 Ben Levenson 2001-10-19 15:22:07 EDT

I've received the same backtrace while using kmail as well.

Comment 8 Josep Guallar-Esteve 2001-10-19 15:36:22 EDT

I think that 53522 is actually the same bug.

Comment 9 Jakub Jelinek 2001-10-19 16:43:00 EDT

If all backtraces have XCreateIC in close above the segfault,
it might as well be the infamous "thou shalt not mix 0 and NULL
arguments to varargs functions on IA-64", since XCreateIC is a
varargs function. Typically:
foo(A a, ...) { ; while (va_arg (v, void *)) != NULL) { } }
bar() { ; foo(1, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0); }
would work on all arches but IA-64, where that 0 might result in
garbage in upper 32 bits on the stack.
Looking at XCreateIC, it e.g. calls _XIMCountVaList which does
exactly that, dunno what Qt is actually doing, can somebody please
check it out (be it under debugger or by source inspection)?

Comment 10 Ngo Than 2001-10-19 17:15:06 EDT

update qt-2.3.1-7 fixes this problem.
