Bug in Type command?

[blmara]

Hi! While testing my program I installed MemGuard (v.1.15) and used it without any arguments. The output was catched with Sashimi. Then I started to get a MemGuard hit shown below every time I use AmigaOS Type Command (for example, using for displaying the Startup-Sequence). A bug in the Type command?

Confirmed on latest betas and added as BZ #8238

fixed too

MemGuard is a nice little tool, isn't it?

@Trixie

I go through all os components by it, and almost all what i find out (there was 4 or 5), are fixed. But together with memguard i also use debug-kernel with munge, and that helps even more.
