--- Comment #12 from Orgad Shaneh <orgads at gmail dot com> ---
I've noticed similar behavior with passing arguments to cc1plus and cc (GCC
8.1.0).

This short script demonstrates the bug:

#!/bin/sh
touch file.h
echo "-g -O0 -w -m32 -fexceptions -x c++-header -o file.gch -c file.h" > resp
seq -f '-IC:/Some/Very/Long/Path/With/Many/Components/%g' 1 1000 >> resp
g++ @resp
# g++.exe: error: CreateProcess: No such file or directory

g++ --verbose output:
Using built-in specs.
