Bug#908109: clang-6.0: AddressSanitizer: SEGV on unknown address ... in _dl_get_tls_static_info

[Jakub Wilk]

Package: clang-6.0
Version: 1:6.0.1-6

Programs built with -fsanitize=address seem completely broken:

   $ printf '#include <stdio.h>\nint main(int argc,char**argv){printf("Hello world!\\n");}' > hello.c
   $ clang-6.0 -fsanitize=address hello.c -o hello
   $ ./hello
   AddressSanitizer:DEADLYSIGNAL
   =================================================================
   ==7617==ERROR: AddressSanitizer: SEGV on unknown address 0xf7ee9430 (pc 0xf7ee9444 bp 0xff9c367c sp 0xff9c363c T16777215)
