I have 17Go of swap space but only 1Go of real RAM. And every time i try to compile, i run into this error

[ 97%] Linking CXX executable ../../runtime_output_directory/merge_large_tests-t
/usr/bin/ld.gold: out of memory
collect2: error: ld returned 1 exit status

make: *** [all] Error 2

How to repeat:
I cloned the repository, then create the build directory, get into it. I ran cmake :

Then I ran make -j4, it crashed. I also tested with make

This issue got into the released tarball of 8.0.18 (mysql-boost-8.0.18.tar.gz)

The issue is then triggered on Fedora on ARMv7hl.


I am a Fedora maintainer who takes care of the community-mysql package.
Without the successful build for the armv7hl arch, I can't build and release the update to 8.0.18 into the Fedora.
Without the fix or workaround it will block any further affected version from entering Fedora.


The issue looks like this:

I have a interesting observation though: the issue is not triggered on the Fedora 29. So there may be chance to trace the issue to a specific package which changed (as all of them did) between F29 & F30.

I can try some, if you give me a tip. However the armv7hl builds are considerably slow, so finding it by random (check each buildroot package) is a no-go.

I disabled liking with GOLD in Fedora on Armv7hl, until fix is found.


Without GOLD, if build fine.

gold seems to be problematic on several archs, would make sense to disable
gold completely or use is on x86_64 only.

gold as default linker was added for faster build times I think, 
these days lld (the LLVM linker) would any way be more naturally choice
for a performant linker.

Posted by developer:
Fixed in 8.0.19.

The GNU gold loader could cause memory exhaustion on some platforms.
Now it is used by default only on Intel 64-bit platforms.
