This sounds like a write buffer overflow in libarchive. It would be
great to have the call to the ar command and the input data.
Quoting Jung-uk Kim <[email protected]>:
emulators/virtualbox-ose is failing on head for some time and I found ar
is causing the trouble. The earliest failures noticed by package
builders are here:
http://docs.freebsd.org/cgi/mid.cgi?201706170249.v5H2nUVZ039286
http://docs.freebsd.org/cgi/mid.cgi?201706170238.v5H2cZTZ054493
The core file shows:
(lldb) bt
* thread #1, name = 'ar', stop reason = signal SIGSEGV
* frame #0: 0x00000000004ac850 ar`memchr + 16
frame #1: 0x000000000044359a ar`strstr + 1082
frame #2: 0x000000000040649f ar`archive_write_ar_header + 2095
frame #3: 0x0000000000409423 ar`_archive_write_header + 259
frame #4: 0x00000000004051eb ar`write_archive + 3995
frame #5: 0x0000000000402be6 ar`yyparse + 1190
frame #6: 0x0000000000402715 ar`ar_mode_script + 69
frame #7: 0x0000000000400cdc ar`main + 2140
frame #8: 0x000000000040035f ar`_start + 383
I am not sure whether ar or libarchive is culprit here.
Any idea?

Hello,
I installed FreeBSD 12-CURRENT on my new laptop DELL Inspiron, because
FreeBSD-11 does not work ACPI
correctly. Apparently everything working, but to build VirtualBox is
occurring the following error:

It seems something is wrong with ar on head since ino64.
Does anyone know how to fix the problem?
I am not sure how to fix it but I worked around it by
replacing/usr/bin/ar with the one from 10.3.
