Yes, I read that.

I was first trying with probesize 10000, then increasing to 100000.
Finally, I increased it to 1000000, but that made ffmpeg segfault. So I
gave up using playing with probesize.

Actually, it segfaults for all probesizes between approx 650000 and 1040000.

This looks like a bug in ffmpeg.

-probesize 9M works fine.

Yes, it does work. And 9000000 works as well (so it is not a command line
parsing bug).

Thanks for pointing me in the right direction.
