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

[Diana Picus via llvm-commits]

Hi Valentin,

I tried to reproduce this in a Ubuntu Focal container with gcc 9.3.0
installed via apt (and no multilib afaict) and I'm not seeing any failures.
It also seems to work in Compiler Explorer: https://godbolt.org/z/nq8czercf
I think the issue might be limited to your system. If you find some kind of
workaround to get the test to work on your system too I'll be happy to
review any changes.

Cheers,
Diana
