Are you able to test on Windows? Does 32-bit WinRAR on Windows handle such a file?
Under 32bit Windows 10 32bit with 4GB of RAM (Windows shows 3.5GB as usable) I get the same error.
Under 64bit Windows 10 64bit it seemingly works.
However I run Wine 32 under 64bit Linux with 32GB of RAM, so Windows 64/Winrar 32 and Linux 64/Wine 32/WinRAR 32 are kinda equal.
