No, it's still SIGABRT:

> BUF_BEG (current_buffer) &&
> charpos <= ZV)

^^^^^^^
"sig=6" means SIGABRT (you can see that in your system's header files,
probably in /usr/include/bits/signum.h).
> 364 signal (sig, SIG_DFL);
This just shows the source line where Emacs stopped due to the fatal
signal. It has nothing to do with the signal itself.

Thanks, I installed a change which should fix this. Please try the
latest release branch.

Org copies the snippet to a separate buffer, turns on nim-mode in that
buffer, then indents the text, and finally copies the text back. The
problem happened because the window-start position was not updated
during this dance, and still had the value suitable to the Org buffer,
which is outside of the valid positions in the temporary edit buffer.
