Subject: e2fsprogs segfaults during make check

Hello,
     I found a problem while creating e2fsprogs rpms. Few of the tests
fail with segfault during make check. The tests are d_loaddump, f_dup4,
f_imagic_fs and r_resize_inode. This failure is only seen on rhel5,
x86_64. 
      On further searching I found that this error can reproduced when
e2fsprogs is configured with shared elf libraries. For example,
configure --enable-elf-shlibs, make; make check 
And this problem is seen from 1.41.7 version onwards.

Any ideas/comments ?

Thanks,
Girish
