Segfault in ld.so - MMX related?

[Frank McIngvale]

Hi, I'm trying to track down a segfault that is only triggered
by certain versions of binutils, namely:

   binutils-2.11.90.0.27 - OK
   binutils-2.11.90.0.31 - OK
   binutils-2.11.92.0.5 - Segfault
   binutils-2.11.92.0.10 - Segfault
   binutils-2.11.92.0.12.3 - Segfault

The reason I'm mailing bug-glibc is that it looks like
it is crashing during dynamic linking. i.e., if I
set LD_DEBUG=symbols, it crashes here:

  18549:  symbol=X11_CreateYUVOverlay;  lookup in file=./t
  18549:  symbol=X11_CreateYUVOverlay;  lookup in 
file=/usr/X11R6/lib/libsmpeg-0.4.so.0
  18549:  symbol=X11_CreateYUVOverlay;  lookup in 
file=/usr/X11R6/lib/libSDL-1.2.so.0
  Segmentation fault (core dumped)

My test program is:
  t.c:
     main() {}
  gcc -o t t.c -lsmpeg -lSDL -lpthread

I've tried this with both gcc-2.95.3 and egcs-1.1.2 (i.e. recompiling
binutils & libsmpeg each time), with the same results. (Also with Linux
kernel 2.2.20 and 2.4.16). I've even recompiled my entire system to make
sure there wasn't a version mismatch somewhere.

Here's the odd part: If I compile libsmpeg with "--disable-mmx", the
segfault goes away.

I am using a stock glibc-2.2.4. I emailed H.J. Lu, but he was unable to
reproduce this bug on a recent RedHat. Have there been any CVS patches since 
2.2.4
that might have fixed a dynamic linker/MMX bug? Anything else I can try?

(Please cc: me on replies, if this is a mailing list.)

thanks,
