[New-bugs-announce] [issue35261] readline.c: PyOS_InputHook not protected against SIGWINCH

[pmpp]

New submission from pmpp <pmpp.pub at gmail.com>:

when using PyOS_InputHook from within readline module
two signals are to be handled SIGINT and SIGWINCH
SIGINT is really usefull in case hook has a problem though in some case it should be nice to prevent it too (async loop in repl background) 

but SIGWINCH is an annoyance and often lead to interpreter crash.

sample file:
 linux crash test under ubuntu bionic python 3.7.1 gcc7
