Re: sed oddity

Siggy,

This may be related to a problem I had with 1.2.13 < kernels < 1.3.56. I
believe it may be/have been a kernel bug.

If a program is run and then its image is changed on disk, sometimes the next
time it is run it will dump core. For example:

  $ gcc foo.c -o foo
  $ ./foo
  ...normal foo output...
  $ vi foo.c
  $ gcc foo.c -o foo
  $ ./foo
  ...foo dumps core...
  $ rm foo
  $ gcc foo.c -o foo
  $ ./foo
  ...normal foo output...

I haven't had any problems since I upgraded to 1.3.56.
