# 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-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
