[PATCH] D109227: [flang] GET_COMMAND_ARGUMENT(LENGTH) runtime implementation

[Diana Picus via llvm-commits]

Hi Valentin,

Thank you for the report!

I've been googling that error message a bit and all I could find were posts
related to compiling with -m32 on a 64-bit system. However the test is
definitely not passing -m32 and you seem to be using an x86-64 compiler, so
I'm not sure what the issue is. Would it be possible for you to try some
experiments on your end, e.g. check if you have libc-header-start.h
anywhere on your system, or installing gcc-multilib?

Thanks,
Diana
