Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
I encountered the problem while using arm-none-eabi-gcc 8-2018-q4 on a Windows
10 64-bit.
To reproduce it, create an empty main.c and try to compile it with -g or -g3:
C:\Users\ilg\tmp>"C:\Users\ilg\AppData\Roaming\GNU Tools ARM
Embedded\8-2018-q4\bin\arm-none-eabi-gcc.exe" -flto -g main.c
c:/users/ilg/appdata/roaming/gnu tools arm
embedded/8-2018-q4/bin/../lib/gcc/arm-none-eabi/8.2.1/../../../../arm-none-eabi/bin/ld.exe:

Linux and macOS builds seem ok, only the mingw-w64 build is affected. Previous
Arm releases, using GCC 7, were ok on Windows too, the problem occured after
switching to GCC 8.
