Description Vasile M. 2022-05-02 07:04:36 UTC
Tracing child processes (-f) does not work in some cases.

Steps to reproduce:
ltrace -f -e getenv bash -i -c lsblk

Output:
failed to init breakpoints 7028
couldn't reinitialize process 7028 after exec
double free or corruption (top)
Aborted

Note: It works without the -f parameter.
Comment 1 Jonas Stein gentoo-dev 2022-05-03 21:48:53 UTC
This should also go upstream. 
Unfortunately:
https://gitlab.com/cespedes/ltrace/-/issues/8

Perhaps we have luck and other distributions have a patch already.

emerge --info would be useful too.
Comment 3 Marek Szuba (RETIRED) archtester gentoo-dev 2022-05-03 22:06:38 UTC
Please re-run ltrace with full debugging output and post the results here to see what actually fails. For me, the command you have posted works fine - even as an unprivileged user.

Comment 6 Marek Szuba (RETIRED) archtester gentoo-dev 2022-05-29 22:42:04 UTC
Try as I might I simply cannot reproduce this on any of my Linux boxes, regardless of the distro or even the architecture. Seeing as searching the Web for mentions of ltrace reporting double free or corruption appears to suggest this is its way of indicating having failed to exec a subprocess correctly, I would suggest checking if any security rules or components on your system might get in the way - but that's all I've got, sorry.
