Thats not a bug, thats normal. this happens with all dynamic libraries,
they are mapped in memory, so any disk change will alter all the running
process with dlopened files.

I dont know if it's exploitable, but is cool :)

I found this 'feature' few days while working with gstreamer pipelines
and reinstalling plugins on top of one of the running ones. Producing
random segmentation faults and exceptions. (maybe putting a
fullbreakpointed library will make the process trap) :)

Did you ever played with this? Looks interesting .. dynamic library code
injection in runtime. ;)

I have changed the ABI, so you need to make clean before.
