Anything that can generate 6kB lines in your complation buffer should
do. Try calling a shell script that writes the long line. For me, it
was a long compilation line from "make".
Indeed! The attached script 'prints' 6x1024 'x' characters, and on
GNU/LINUX KUBUNTU 8.04.02 it takes:
4 seconds with Emacs CVS LESS THAN OR EQUAL TO (<=) 20090129 15:30
2:15 minutes, i.e. 60x2+15=135 seconds with Emacs GREATER THAN OR EQUAL
TO (>=) 20090129 15:40!
To reproduce:
$ emacs -Q &
M-x compile
C-a C-k
./test_script-6KB.sh
I was also able to narrow it down to around that date.
cvs up -D 2009-01-29
works fine with my test case,
cvs up -D 2009-01-30
see above...
Cheers,
Angelo.
