# This test case creates a situation where the crate loader would run
# into an ICE when confronted with an invalid setup where it cannot
# find the dependency of a direct dependency.
#
# The test case makes sure that the compiler produces the expected
# error message but does not ICE immediately after.
#
# See https://github.com/rust-lang/rust/issues/83045
# This is a platform-independent issue, no need to waste time testing
# everywhere.
# only-x86_64
# only-linux
# NOTE: We use BARE_RUSTC below so that the compiler can't find liba.rlib
# If we used RUSTC the additional '-L TMPDIR' option would allow rustc to
# actually find the crate.
#
# We check that we get the expected error message
# But that we do not get an ICE
