I tried 'Edit , | man 2 9p' in the tag of an acme window and got:

panic: D2B called on non-block 11a8c8 (double-free?)
acme 1436: suicide: sys: trap: fault read addr=0x0 pc=0x0003aed5

and for fun:

Awesome! another thing, have you ever tried to "Get" a nil string(when you deleted the previous filename)? It's no biggie because I know to avoid the error, but it might be interesting nevertheless.

I just had acme suicide while editing a file -- some voodoo
combination of backspace, right arrow, and shift, I think.
Tiny keyboard, fat palm. :)

acme: text.type backspace: couldn't find destination for message
acme 354384: suicide: sys: trap: fault read addr=0x0 pc-0x0003adb5

Anyone interested in a snap to debug this further?

Cheers,

Sam

Acme suicided when I executed "Edit x/^/c/* /" in a tag bar.

acme: no window owner: '.../genpunc.9.0' does not exist
acme 149313: suicide: sys: trap: fault read addr=0x0 pc=0x0003b286

Logged in with dt2k(latest from CVS), which so far has been rock solid.
