R devel - Nov 2023 - Segmentation fault early in compilation of revision 85514

When trying to compile R on Windows 10 64-bit using LTO as I always do, I
encountered a segmentation fault early in the compilation. I am uncertain
as to what it means (please see below for error extract). I am using the
most recent version of Rtools43 (5863) and updated its libraries prior to
starting the build. My EOPTS is " -march=native -pipe -mno-rtm" and my
LTO/LTO_OPT/LTO_FC/LTO_FC_OPT is "-flto=1 -fuse-linker-plugin".

Any explanation or suggestions would be appreciated.

Thank you,

Avi

Avi,

Might be toolchain-dependent, might be options-dependent--it built fine here.
Easier for you to vary option two so maybe try that?
