Hi @stephenong
I've reproduced.
This relies on arm none abi gcc toolchain:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89249

I've already applied a patch in the released version, unfortunately it seems it is not enough.

The only way is to install in a path without space, to do this you can use the portable feature of Arduino IDE:

Sorry for this.

The workaround of installing portable Arduino IDE works. Thanks!
