mbed cli - compile - module size output failing

[JanneKiiskila]

The module size printout is failing with Mbed OS 5.7.6 (and 5.8.0).

mbed cli version 1.5.1.

Repro steps

git clone git@github.com:ARMmbed/mbed-bootloader.git
mbed deploy
mbed compile -m UBLOX_C030_U201 -t GCC_ARM --profile=tiny.json -c

Correct output

just change the Mbed OS to a newer version.

cd mbed-os
git checkout mbed-os-5.7.6
cd ..
mbed compile -m UBLOX_C030_U201 -t GCC_ARM --profile=tiny.json -c

and you get this instead of the correct output.

Seems to me the parsing is somehow failing when the Mbed OS is updated.

[JanneKiiskila]

Tried deleting the BUILD folder completely to avoid some "left-behind" things, but that doesn't help either.

@cmonr and @theotherjimmy can provide more information on this

[screamerbg]

@JanneKiiskila what about one of the least mbed OS 5.8?

[cmonr]

@JanneKiiskila This particular problem was fixed with 5.7.7.

A PR was mistakenly merged into mbed-os because oddly enough there's no test to verify that the compiled output structure does not change.

Can you share the steps you did to test this with 5.8.0, because as it stands, I actually can't compile the example with mbed-os checked out to mbed-os-5.8.0, and want to know how you verified this.

[JanneKiiskila]

Just tried mbed-os-5.8.0 and it's OK.
