Comment (by Tarrasch):

 By the way, I found a very similar duplication in `rts/sm/Compact.c`.
 Would an issue+patch be appreciated for that file as well?

 Or you can easily find the occurrences yourself if you prefer:

 {{{
 $ your-favorite-grep-tool 'while \(size \> '
 ...
 rts/sm/Compact.c
 272:    while (size > 0) {
 318:        while (size > 0) {
 398:    while (size > 0) {
 ...
 }}}
