GCC 8: build fails with LTO

[john]

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\Mike\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.

I believe there is documentation online about fixing this. You need to add a reference to the plugin. Also, I believe this is a duplicate.

Marc, I tried googling around and found nothing. Some links would be greatly appreciated.

Google "lto-wrapper failed", or "stack overflow lto-wrapper failed".

I had the same problem for gcc 8 2018-q4/8.2.1.
Tried the suggestions none works.

[john (jkovach)]

Jerry, same here. I believe this is a genuine new bug.

Hi john,
Can you provide reduced testcase to with corresponding command line options so I can reproduce this issue ?
