[Bug binutils/10363] New: objdump -T crashes on corrupted file

[doko at debian dot org]

[forwarded from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=487963]

seen with 2.18, 2.19, and trunk 20090704 on x86-64-linux-gnu:

On amd64, the attached file causes objdump -T to crash.

   It's probably possible to create a similar file on another
architecture. Here is how I did:

  ~% zzuf -j4 -qv -s0: -r0.000001:0.01 -c objdump -T /usr/lib/libm.so
  zzuf[s=0,r=1e-06:0.01]: launched `objdump'
     [...]
  zzuf[s=785,r=1e-06:0.01]: launched `objdump'
  zzuf[s=786,r=1e-06:0.01]: launched `objdump'
  zzuf[s=787,r=1e-06:0.01]: signal 11 (SIGSEGV)
  ~% zzuf -s787 -r0.000001:0.01 < /usr/lib/libm.so > /tmp/foo.so
  ~% objdump -T /tmp/foo.so
     [...]
  [1]    7998 segmentation fault  objdump -T /tmp/foo.so
