Description
Version : ffmpeg version N-40824-g31dfe20
Job : pcm_dvd --> pcm_s24le
Args[0] : -i E:\VIDEO_TS\VTS_01_1.VOB test.wav
Args[1] : -acodec pcm_s24le -i E:\VIDEO_TS\VTS_01_1.VOB test.wav
Result[Win7] : pcm_s16le
Result[Ubu] : pcm_s32le
Desc : Sourceformat (24Bit 96kHz) detected, but ffmpeg@windows switch to pcm_s16le for output. FFmpeg@ubuntu create the wav-output with 24Bit.
Set the codes pcm_s24le explicit don't help:

That's right, my mistake:
The codec param have to be between the input\output params.
Thanks for help.
BTW: How can I close the ticket now?!

I wonder if ffmpeg should always choose a suitable pcm encoder for the wav container.

"suitable" is not really a clear definition.
16-bit is the most compatible by far, defaulting to lossless instead might be better but I'm not sure.

Summary: | Different results win7 vs. linux on pcm_dvd --> pcm_s24le → pick suitable pcm encoder for wav container |

You could try to put "-acodec pcm_s24le" in front of "test.wav" where it has the effect that you want.
