Description

MC (4.6, 4.7) work fine on system with glibc 2.7.
When i upgrade glibc to 2.11 then internal viewer and editor not work, absolutely no reaction on all files except archives. If open archive, then error "cannot spawn child process".

I downgrade to glibc 2.7 and again MC work fine.
It`s a same - http://www.linux.org.ru/news/opensource/3334500/page4 (search keyword - "child"). I thing something wrong with pipe calls.

Tnx! (sorry for English)

Sorry, can't reproduce. Can you build latest git version of mc with debug info enabled to validate bug still exists? I'd like to gather more info from mc process when it hangs:

  • pstree status for mc subtree
  • gdb -p $mc_pid

    bt all

Build and install latest git version 4.7.1-145-gbccf557. Still not work.

~ $ pstree <pid>
mc---bash
