Hi I found out that the patch cc75d373fdb9668f367959f99f0b67e056a6c18a (Enable secureplt by default for alpha-linux) committed to binutils git breaks ld on alpha.
This is a minimalized testcase that shows the breakage: http://people.redhat.com/~mpatocka/testcases/alpha-ld-bug/ld-bug.tar.xz To reproduce the bug, run ./ld-bug.sh to perform the linking, then run the resulting binary: LD_PRELOAD=./libots.so ./memset The bug happens when using the Compaq C Compiler (ccc) on Alpha Linux (it can be downloaded from ftp://ftp.compaq.com/pub/products/C-CXX/linux/compaq_c/ ). When using optimization, Compaq C replaces a call to memset with a call to _OtsZero located in libots.so. The above patch breaks ld in such a way that the resulting program crashes when performing the dynamic call to _OtsZero.
