In CVS current, Mule on X crashes immediately. This may be related to
Japanese hardware; the keysym that blows up is 1223 decimal, which
puts it in the KATAKANA_JISX0201 range. (Cf x_keysym_to_character(),
src/event-Xt.c:211.)
`xemacs -nw -vanilla' does not crash.

I guess so.
There was the same crash report from himi.
"assertion of CHARSET_BY_LEADING_BYTE fails on gcc-2.95.2 20000220."

I don't know why it doesn't happen to me (I'm using Debian
woody). There are already some hack to remedy GCC optimizer
bug which I don't like very much because it tend to worsen
readability. But if it happens to many people, something
should be done.

This was my change.
I can't reproduce this, and of course I have gcc 2.95 as well.
If I do
xmodmap -e 'keysym F10 = F10 kana_NU'
Then press [(shift f10)], I see a real live kana character in my
xemacs buffer.
I would like to keep the arg of CHARSET_BY_LEADING_BYTE as is, since
it is actually logically a bufbyte.
SJT> GCC bug, maybe?
Maybe. Is it possible inline functions with unsigned char arguments
don't have proper conversions from int?
Could you investigate some more?
If you load a cyrillic keyboard mapping before starting X, do you have
the same problem? Is it dependent on compiler flags?

No, it's not, in this case; it's an enum LEADING_BYTE_OFFICIAL_1. The
point being that there are several ways to hit that assert, and not
all of them pass through a buffer. From the comment in the preceding
version (which you should not have deleted; you should have disagreed
with it), that's exactly the reasoning that led to the arg being an
int in the first place.
I agree that we _wish_ it were a Bufbyte, but if we were all that
confident of that, we wouldn't need the assert. A real buffer byte
that gets fed to that assert presumably was acquired via
VALIDATE_CHARPTR_BACKWARD and friends, and already passes the assert.
IIRC, leading bytes are also used to identify charsets in redisplay
internals. It's not so hard to imagine a programming error in which
an Emchar gets put somewhere that eventually ends up hitting that
assert, is it?
SJT> GCC bug, maybe?
mb> Maybe. Is it possible inline functions with unsigned char
mb> arguments don't have proper conversions from int?
As karlheg would say "you tell me and we'll both know". I'm not a
member of the bar in C.
Note that as I mention above the argument also has to be converted
first from enum LBO1 to Bufbyte; this would imply a GCC bug, though,
because that conversion should already be a fact when the assert is
hit.
I'm more suspicious of this type_checking_assert. What is it? Is
this a C9x thing?
mb> Could you investigate some more?
Yes. You've probably seen Yoshiki's message already, but there's
himi's report "assertion of CHARSET_BY_LEADING_BYTE fails on
gcc-2.95.2 20000220." himi says -O0 wins for him and provides
assembler output to show why. I haven't tried it, will do so if you
insist.
Yoshiki's suggestion of -fno-gcse in that thread does NOT win for me,
it pukes on the same assertion with the same C backtrace that Himi and
I have both posted (I checked that Himi's is the same).
mb> If you load a cyrillic keyboard mapping before starting X, do
mb> you have the same problem?
Yes, I do (on keysym 1738, which is in the Cyrillic range according to
the logic in event-Xt.c).
mb> Is it dependent on compiler flags?
Any further suggestions for compiler flags to try?
Better hurry, XF86 4.0 just showed up in Debian woody, and I probably
won't have a reliable workstation to test on for a couple of weeks
after "upgrading" to that :-P
