I do believe, and removing precisely the listed lines fixes this for me, that the cause is that… https://github.com/MirBSD/mksh/blob/12273466d30e7ac98b483ba3b78f9c27de8cf67a/exec.c#L859-L866 … is trying to duplicate, but the other way round, what… https://github.com/MirBSD/mksh/blob/12273466d30e7ac98b483ba3b78f9c27de8cf67a/jobs.c#L591-L599 … already achieves: implement the following POSIX paragraph: 2.11. Signals and Error Handling If job control is disabled (see the description of [212]set -m) when the shell executes an asynchronous list, the commands in the list shall inherit from the shell a signal action of ignored (SIG_IGN) for the SIGINT and SIGQUIT signals. In all other cases, commands executed by the shell shall inherit the same signal actions as those inherited by the shell from its parent unless a signal action is modified by the [213]trap special built-in (see [214]trap) Can you please delete the lines from exec.c and see whether this fixes your problem and doesn’t introduce any regression? I’ll do a matching upload soon (once over the Influenza vaccine’s reaction, i.e. once I can use my arm again without too much pain), but if you can test it before that I can close the bug with confidence in the upload. bye, //mirabilos -- 18:47⎜<mirabilos:#!/bin/mksh> well channels… you see, I see everything in the same window anyway 18:48⎜<xpt:#!/bin/mksh> i know, you have some kind of telnet with automatic pong 18:48⎜<mirabilos:#!/bin/mksh> haha, yes :D 18:49⎜<mirabilos:#!/bin/mksh> though that's more tinyirc – sirc is more comfy
