Description Bernhard Rosenkraenzer 2010-06-11 09:35:48 UTC 
When using gold (Last tested version: GNU gold (Linux/GNU Binutils 2.20.51.0.9.20100526) 1.9), the 
check done in various autoconf scripts (checking whether a statically linked program can dlopen itself) 
hangs forever, with conftest taking up 100% CPU time.

Switching the linker to the old ld fixes it.

More information on the issue (including the theory that it is related to gold's handling of 
STT_GNU_IFUNC symbols) can be found at:

Comment 1 Ian Lance Taylor 2010-06-11 13:10:44 UTC 
gold does not yet support STT_GNU_IFUNC symbols at all.
Comment 2 Ian Lance Taylor 2010-08-04 08:58:17 UTC 
This is definitely an STT_GNU_IFUNC issue.
