1705913 - ASan build on debian failing with "ld.lld: error: duplicate symbol: operator delete"

Status: RESOLVED WORKSFORME

(Firefox Build System :: Toolchains, defect)

Description

[Tyson Smith [:tsmith]]

Lee has been seeing this trying to do ASan builds locally (on Debian).

This is from a clobber build. ./mach bootstrap was also used recently.

62:05.48 ld.lld: error: duplicate symbol: operator delete

He also tried a mozconfig that I am using but still hit the issue. I am unable to reproduce this on Ubuntu.

Any ideas what might be going on?

Comment 1

[Tyson Smith [:tsmith]]

I tested with a fresh install of Debian 10 in a VM and followed the build instructions. I had no issues creating an ASan build.

Comment 2

[Mike Hommey [:glandium]]

Is this still an issue?

Comment 3

[Tyson Smith [:tsmith]]

Good question. I wasn't able to reproduce the issue.

Lee have you tried an ASan build lately?

Comment 4

[Tyson Smith [:tsmith]]

Note: adding the following line to my mozconfig reduces the build time down to ~10 minutes to test a clean build.

ac_add_options --enable-optimize="-OO"

Comment 5

[Lee Salzman [:lsalzman]]

I believe it seems to build here now.

Comment 6

[Mike Hommey [:glandium]]

Let's close, then. Please feel free to reopen if you can reproduce.
