10:41 < TimToady> m: say "𢡊"
10:41 <+camelia> rakudo-moar 691b39: OUTPUT«(signal SEGV)»
10:42 < TimToady> jnthn: ^^ there's another glitch :)
10:43 < timotimo> can you also make that with a \x literal, so that i can
more easily copy-paste it?
10:47 < TimToady> m: say "\xfacf"
10:47 <+camelia> rakudo-moar 691b39: OUTPUT«(signal SEGV)»
10:47 < TimToady> m: say "\xfad0"
10:47 <+camelia> rakudo-moar 691b39: OUTPUT«(signal SEGV)»
10:48 < [Coke]> O_o
10:48 < TimToady> m: say "\xfad9"
10:48 <+camelia> rakudo-moar 691b39: OUTPUT«龎»
10:49 < TimToady> m: say "\xfad8"
10:49 <+camelia> rakudo-moar 691b39: OUTPUT«齃»
10:49 < TimToady> m: say "\xfad7"
10:49 <+camelia> rakudo-moar 691b39: OUTPUT«(signal SEGV)»
10:49 < TimToady> there's the boundary
10:50 < TimToady> that trailing boundary, facf is the leading boundary
10:50 < TimToady> timotimo: thanks
10:51 < timotimo> er, thanks why exactly?
10:52 < TimToady> for copy-pasting it :)
10:52 < timotimo> damn, you expect me to fix that bug now? ;)
10:52 < TimToady> or at least for wanting to copy-paste it :)
10:53 < timotimo> 48543 const MVMint32 *pcs =
comp_p[plane][upper][lower];
10:53 < timotimo> the values of the indices are, respectively, <optimized
out>, <optimized out>, and <optimized out>
10:53 < timotimo> :P
10:53 < TimToady> cool!
10:54 < TimToady> "Nobody will ever use those characters!"
10:54 < timotimo> 2, 126, and 211
10:55 < timotimo> (gdb) print comp_p[2][126]
10:55 < timotimo> $5 = (const MVMint32 **) 0x0
10:56 * TimToady notes that those are, in fact, plane 0 characters
10:56 < timotimo> so ... do we actually expect there to be something?
10:57 < TimToady> I wouldn't expect to find something in plane 2 for them,
no :)
11:01 < timotimo> i personally haven't a clue what that particular piece of
code is precisely supposed to achieve; you said it's supposed to
be plane 0, do you know why it'd get plane 2 instead?
11:02 < timotimo> given plane is just (l >> 16) & 0xF
11:03 < TimToady> maybe upstream, the same remapping thingy that turns 艹
into 艹 is turning those compat chars into something in plane 2?
11:03 < TimToady> but then they should find something

11:06 < timotimo> that's the full backtrace of the thing you originally
made copy-pastable
11:06 < TimToady> m: say "𢡊"
11:06 <+camelia> rakudo-moar 691b39: OUTPUT«(signal SEGV)»
11:06 < TimToady> that's the actual plane 2 character that can't print
