24.0.50; visiting an EPS file with preview TIFF image and with one long line |

Hello!
I have an EPS file created by Adobe Illustrator 15 with a "DOS EPS
Binary File Header" according to 5002.EPSF_Spec and a TIFF preview at
the end, in mac-roman-mac encoding. Size: 643 KB. When I visit that
file from a dired buffer in PostScript DocView View mode and scroll
down near the end of the PostScript section where the TIFF preview
starts, it happens that GNU Emacs becomes inoperable for seven hours
while consuming all remaining CPU power. The first line of the TIFF
section, starting with II*, is approximately 314,899 characters long
(GNU Emacs is a bad tool, it counts ASCII NUL ^@ as two columns).
Rendering this in a window of 55 lines and around 120 columns takes
these 7 h. And more: GNU Emacs creates a #file.eps# backup file,
larger in size (50 %) than the original file. Is that the expected
behaviour?

Yes, when Emacs catches a fatal signal, it auto-saves. This is normal
behavior.
Closing. Thanks for looking into this.
