yoichio@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!

Confirmed.

I confirmed the crash but the case doesn't relate to my change.
Could you bisect?

manoranjanr@ Could you please look into this issue.

Would you mind looking into this kojii?

The CHECK was added in issue 722873.

Oh, but then the code was branched for first-line and the CHECK was copied to the first-line code path. Maybe not the original cause but due to first-line.

Yeah, the problem is in the first-line code, sorry for the noise.

Fix first-line text-transform workaround when start is not zero

r526281 added a workaround for when text-transform shorten
the string, but did so only for when inline_text_box_.Start()
is zero.

This patch extends the workaround for when inline_text_box_.
Start() is not zero.
