Bug#1017440: pahole: Several tools just segfault

Show all headers | View raw

Package: pahole
Version: 1.23-2
Severity: serious

Hi!

Many of the tools simply segfault when executed. On a shared library
with debugging symbols:

  $ codiff libsysfs.so.2.0.1 libsysfs.so.2.0.1
  Segmentation fault (core dumped)
  $ dtagnames libsysfs.so.2.0.1
  Segmentation fault (core dumped)
  $ prefcnt libsysfs.so.2.0.1
  Segmentation fault (core dumped)
  $ scncopy -s data -o output libsysfs.so.2.0.1
  Segmentation fault (core dumped)
  $ syscse libsysfs.so.2.0.1
  Segmentation fault (core dumped)

On a stripped library:

  $ codiff /usr/lib/x86_64-linux-gnu/libbsd.so.0 \
           /usr/lib/x86_64-linux-gnu/libbsd.so.0
  Segmentation fault (core dumped)
  $ dtagnames /usr/lib/x86_64-linux-gnu/libbsd.so.0
  Segmentation fault (core dumped)
  $ prefcnt /usr/lib/x86_64-linux-gnu/libbsd.so.0
  Segmentation fault (core dumped)
  $ scncopy -s data -o output /usr/lib/x86_64-linux-gnu/libbsd.so.0
  Segmentation fault (core dumped)
  $ syscse /usr/lib/x86_64-linux-gnu/libbsd.so.0
  Segmentation fault (core dumped)

Some even with no arguments:

  $ dtagnames
  Segmentation fault (core dumped)
  $ prefcnt
  Segmentation fault (core dumped)

Thanks,
Guillem
