with printf() calls, and even write(1, "", 0); right before it made it
go away. Given that this code has run on 32 and 64 bit, big and little
endian, glibc musl and bionic, and on a target that's both nommu and
cares about alignment?
Are you sure that "gcc is doing something [wrong]"? Do you think it could
be a QEMU bug? Can you provide some information about your tool chain?
Because I'm still halfway through teaching toysh about all the ${}
constructs. (Also, remind me to stick echo -e '\e[?7h' at the start of
my init script to undo the STUPID wordwrap disable escape that qemu's
bios outputs, which screws up bash's command line history too!)
How awful. It baffles me every time bash manages to mishandle unprintable
output from a command such that it somehow becomes command line input
which bash then attempts to execute! I wish I knew how to prevent that.
