The following reply was made to PR bin/171604; it has been noted by GNATS. From: Andrey Simonenko <simon@comsys.ntu-kpi.kiev.ua> To: bug-followup@FreeBSD.org Cc: Mark Johnston <markjdb@gmail.com> Subject: bin/171604: [patch] LD_PRELOAD set to not absolute path crashes rtld Date: Mon, 17 Sep 2012 18:30:53 +0300 > Ok, so that fixed the segfault at least. I think the LD_PRELOAD handling > is still incorrect. According to rtld(1), if LD_PRELOAD isn't an > absolute path, then LD_LIBRARY_PATH and the standard library path > (/lib:/usr/lib) should be searched. However, we're only searching > LD_LIBRARY_PATH in this case at the moment: That manual page references to "built-in standard directories", but does not define what they are. Previously LD_PRELOAD set to not absolute path worked even for /usr/local/lib (as I understand because of ldconfig called for that directory). I notice that net/proxychains that worked before on RELENG_9 did not work now (it calls any program with LD_PRELOAD=libproxychains.so, just install it and check shell script at bin/proxychains). > The attached patch addresses this problem as well. Yes, it works for /lib at least.
