I don't think this is the right fix. The issue is occurring here with
the rather old Synopsys ARC toolchain, of which we're using version
2019.09. Turns out
that https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/
has much much newer versions available, so the right fix really would be to
upgrade.

Alexey, do you think someone on your side could work on this? Unless
Fabrice you're interested in having a look?

Best regards,

Thomas
