Description Andreas Schwab 2006-04-05 14:15:09 UTC 
From Jörg Sonnenberger <joerg@bec.de>:

When linking PIC and non-PIC object files which access the same thread locale
variable, R_386_TLS_GD and R_386_TLS_IE relocations are merged into a single
R_386_TLS_TPOFF relocation, ignoring the different offset calculations.
ftp://packages.stura.uni-rostock.de/misc/tls-reloc.tgz has a small test case.
It results in a segfault of ld-linux.

I used the new binutils on gcc and glibc. Everything looks OK. Fixed.
