DISCO-L475VG-IOT01A board and mbed-os 5.12.1 with OnLine compiler

The compiler works without error, but the linker gets this fatal error about 80% of the time. If the linker does pass, the L475VG immediately gets a runtime error. 5.12.0 does not do this.

Linker fatal warning:

Error: Warning: L3912W: Option 'legacyalign' is deprecated.
Info: Unable to download. Fix the reported errors...

runtime error:
