Crash on selecting extremely long line about mintty HOT 11 CLOSED

Thanks for the report. I can produce an issue with this, but I'm not entirely 
sure it's the same you reported.

Have you got the 'Clicks place cursor' option enabled? Did you mean triple 
click rather than double click? Where do you see the SIGSEGV? Does it happen 
right away, or does it require a sequence of clicks?

I'm just getting an unresponsive window which does eventually unfreeze again. 
Meanwhile, bash uses 100% CPU. I think what's happening there is that mintty is 
sending thousands of cursor key presses to try to move the command line cursor 
to where you clicked. It's only supposed to do that though when clicking on the 
current command line rather than earlier output. 

i'm sorry, to select the whole "line" (span across multiple lines) that just 
read from file a, it was "triple" not double click.
it happen right after the line (or lines) is selected

i assume it be SIGSEGV because it generated mintty.exe.stackdump
$ cat mintty.exe.stackdump

there's no bash 100% cpu issue here

Thanks for the extra information. So do you have 'Clicks place cursor' on the 
'Mouse' page of the options enabled? Also, what's the size of your mintty 
window, perhaps that's relevant.

ah, i missed a question

'Clicks place cursor' -> no
size: 80cols * 40 rows
size from spyxx: rect: 747x796, client rect: 722x762
font: consolas, 12-point
smoothing: full
locale, charset: zh_CN, UTF-8

Thanks, that's definitely a separate issue from the one I saw then. 
Unfortunately I can't yet reproduce it, so here are more questions.

How did you install mintty 0.8.3? Through setup.exe, from the .zip download 
here, or from source? If the latter, which gcc version did you use?

And could you attach your .minttyrc with all the settings? Perhaps the issue 
depends on a particular combination of options.

through setup.exe, reroduced in windows xp tooo
maybe its only reproduced with Chinese OS?
would it help if i try to reproduce it from a debug built source myself?

You're right, this is language-dependent. I've finally managed to reproduce it 
by changing the system default codepage to CP936.

Looks like it's the code for converting the copied text to RTF that's at fault 
here, because you can work around the issue by disabling the 'Copy as rich 
text' setting on the Mouse page of the options.

Fixed in r1015 on trunk.

I've fixed the separate problem with 'Clicks place cursor' in r1016 on trunk.
