Subject: Running via <ld.so> gives a different executable
Date: Fri, 26 Feb 2021 13:21:34 -0500	[thread overview]
Message-ID: <89538393-2014-85c6-2350-9f02847318a4@gmail.com> (raw)

Happened to discover that, at least under glibc 2.31, if you launch a binary via <ld.so> on linux, the proc exe link is set to <ld.so>.

This causes ps to report the program as ld.so and also breaks (at least) any Qt application that uses QCoreApplication::applicationDirPath()

https://doc.qt.io/qt-5/qcoreapplication.html#applicationDirPath

Reaching out to the mailing list to see if this is I should be opening a bug report about?

Thanks!  -Tyson

PS: Discovered this trying to use <ld.so> --preload on a Qt binary where I couldn't use LD_PRELOAD as it would pollute the forked children.
