Ok it appears I need to run: sudo apt-get install zstd which would install the
correct libraries (I used libzstd-dev before which installed older version). At
any rate, now it creates zst file.

It now finally works!

Oh and one more question: Can you actually attach via GDB? E.g. this part of
the message makes me wonder:

Could not attach to process.  If your uid matches the uid of the target
process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try
again as the root user.  For more details, see /etc/sysctl.d/10-ptrace.conf

Try to run `gdb --pid ...` and see if that works for you.

do you still see this error:

/usr/bin/heaptrack: 174: [: FALSE: unexpected operator

?

What does this give you in your shell:

echo $SHELL
if [ "TRUE" = "TRUE" ] && [ ! -z "$(which zstd)" ]; then echo "works"; fi

Nope, I just git pulled and built with zstd support and exactly the same
problem on 16.04. I attached the output as you require but it's exactly same
error message.

I think I solved this via

Make heaptrack.sh file compatible with dash

Don't use the bashism == to compare strings, use = instead.

Probably a bug I introduced with the addition of zstd support. What shell do
you use? Can you paste the contents of `cat $(which heaptrack)` please - I want
to double-check what it generated.

To workaround this, install zstd development headers, it should both fix this
and make heaptrack faster too :)
