Subject: ld-wrapper and funny bytes in LIBRARY_PATH
Date: Sat, 17 Jun 2017 10:48:27 +0200	[thread overview]
Message-ID: <20170617104827.6eda2dbd@scratchpost.org> (raw)

Hi,

so I'm trying to enable Rust tests and one of their tests does the following (paraphrased) in order to exercise the non-UTF8 linker case (which they want to succeed):

----------------------------------------------
bad_dir := zzz$$'\xff'

all:
        mkdir $(bad_dir)
	cp ... $(bad_dir)/liblibrary.a
	LIBRARY_PATH=$(bad_dir) rustc exec.rs
----------------------------------------------

This fails for us.

strace yields:

[pid 15059] open("/tmp/guix-build-rustc-1.16.0.drv-0/rustc-1.16.0-src/src/test/run-make/linker-output-non-utf8/zzz?/liblibrary.a", O_RDONLY) = -1 ENOENT (No such file or directory)

But:

/tmp/guix-build-rustc-1.16.0.drv-0/rustc-1.16.0-src/src/test/run-make/linker-output-non-utf8 [env]$ ls zzz\377/liblibrary.a 
'zzz'$'\377''/liblibrary.a'

$ ls /tmp/guix-build-rustc-1.16.0.drv-0/rustc-1.16.0-src/src/test/run-make/linker-output-non-utf8/zzz?/liblibrary.a
'/tmp/guix-build-rustc-1.16.0.drv-0/rustc-1.16.0-src/src/test/run-make/linker-output-non-utf8/zzz'$'\377''/liblibrary.a'

How do we best proceed?
