File compile failure

Just tried to use the new release of GNU Arm Embedded to build one of my programs. The build fails at link stage (LTO enabled):

c:/program files (x86)/gnu tools arm embedded/8 2018-q4-major/bin/../lib/gcc/arm-none-eabi/8.2.1/../../../../arm-none-eabi/bin/ld.exe: C:\Users\Jerry\AppData\Local\Temp\ccaZJHsddebugobjtem: file not recognized: file truncated
collect2.exe: error: ld returned 1 exit status
lto-wrapper.exe: fatal error: arm-none-eabi-gcc returned 1 exit status
compilation terminated.

Anyone could help?
Thanks Jerry
