Hi Nathan:
Double confirmed again, it still ICE to me, but I might miss some info so I
post my env and configure option:
GCC: g:b73f69020f08208d2d969fcf8879bd294a6e3596
Host: x86_64-linux (Ubuntu 18.04)
Target: arm-eabi
Configure option: --target=arm-eabi --enable-languages=c,c++
Bootstrap gcc only
$ arm-eabi-g++
../riscv-gnu-toolchain-trunk/riscv-gcc/gcc/testsuite/g++.dg/cpp0x/variadic-sizeof4.C
-std=c++14
reduced cc1plus command:
$
/scratch1/kitoc/riscv-gnu-workspace/pr94044/arm-eabi/install/bin/../libexec/gcc/arm-eabi/10.0.1/cc1plus
-quiet
../riscv-gnu-toolchain-trunk/riscv-gcc/gcc/testsuite/g++.dg/cpp0x/variadic-sizeof4.C
-quiet -mcpu=arm7tdmi -marm -march=armv4t -std=c++14 -o -
debug info:

Let me know if it still can't reproduce...thanks :)
