--- Comment #1 from A. Wilcox (awilfox) <awilfox at adelielinux.org> ---
I actually hit this.  As a distro maintainer, I started a shell session on 11
December to start porting our base system to PowerPC.  I then started building
Qt 5.7 (and all its dependencies).  Then KDE Frameworks 5.  While building
Phonon, I noticed weird corruption of the build results.

I am using Konsole 16.08.3 with KF 5.28.  When I saved the shell output, it was
in very weird pieces/chunks, like this (the first few lines of the resultant
file, unedited):


storyn.
/t
mp/envi
onment'.
ch is o
 non-c
ass type ‘int’
operator=(const QStyleOptionGraphicsItem&)’ first required here
64 -ggdb -mcpu=G3 -fno-omit-frame-pointer -Wall -Wextra -Wsign-compare -Wundef
-Wpointer-arith -Wvolatile-registe



It seems to me that somewhere, a signed 32-bit integer is being used:

/tmp/konsole-hF4401.history

That `ls -l` was run at 16:15 and Phonon was still building, so all the output
was just being lost.  Actually, the previous output was also being corrupted.
