4Subject: [PATCH] elf: Ignore LD_LIBRARY_PATH and debug env var for setuid for
5 static
6
7It mimics the ld.so behavior.
8Checked on x86_64-linux-gnu.

10[New Test Case]
11elf: Test case for bug 32976
12[https://sourceware.org/bugzilla/show_bug.cgi?id=32976]
13
14Check that LD_LIBRARY_PATH is ignored for AT_SECURE statically
15linked binaries, using support_capture_subprogram_self_sgid.
