Frequent "save_bash_input: buffer already exists for new fd XXX"

[Adrien Nader]

Hi,

I have recently been getting "save_bash_input: buffer already exists for
new fd XXX" very often when running a fairly simple script (really
nothing complicated) with bash 4.3.42.

I have no idea of what could cause this, especially since very similar
scripts work fine.
Which steps should I take to make a more precise bug report?
Also I'm currently at 32C3 and that could help if debugging is needed
since the issue is easy to reproduce on my machine but I don't know if
it would be on others'.
