[Bug-tar] bug in tar 1.13.9x

[Eric Warmenhoven]

Hi,

With every tar file I've tried, when I have the environment variable
MALLOC_CHECK_ set to 2, tar dies with SIGABRT:

rack:~/src/tar $ printenv MALLOC_CHECK_
2
rack:~/src/tar $ tar jxf tar-1.13.93.tar.bz2
Aborted
[Exit 134 (SIGABRT)]
rack:~/src/tar $ rm -rf tar-1.13.93
rack:~/src/tar $ export MALLOC_CHECK_=1
rack:~/src/tar $ tar jxf tar-1.13.93.tar.bz2
malloc: using debugging hooks
malloc: using debugging hooks
free(): invalid pointer 0x8071000!

This has been happening since 1.13.90.

Thanks,
Eric
