LTO linker error with GNU Arm 10.3-2021.07

Tarjeik

I have attempted to upgrade the toolchain on a project for a Cortex-M0+ that requires LTO to fit in flash. The project has built just fine up until now, but after upgrading to the latest 10.3-2021.07 version, the linking stage fails. Here's what the output looks like:

/tmp/cczekWsc.s: Assembler messages:
/tmp/cczekWsc.s:2262: Warning: ignoring changed section attributes for .data
/tmp/cczekWsc.s:2272: Warning: dwarf line number information for .data ignored
/tmp/cczekWsc.s:2277: Warning: dwarf line number information for .data ignored
(repeated hundreds of times)
/tmp/cczekWsc.s:61406: Error: leb128 operand is an undefined symbol: .LVU708
/tmp/cczekWsc.s:61407: Error: leb128 operand is an undefined symbol: .LVU708
/tmp/cczekWsc.s:61425: Error: leb128 operand is an undefined symbol: .LVU730
(also repeated hundred plus of times)

Has anyone seen anything like this before? I tried searching for help on this, but came up blank. I'm unsure about how I should even start approaching this as I was unable to even keep the temporary assembler output from the LTO process.

    I tried to use LTO in a project with a size limitation.
    It turned out that the issues disappeared when I downgraded the toolchain to version 9.2.1.
    I am not sure if the problems are related.
