GnuPG 1.9.95: gpg2 segfaults on build test

Tue Nov 7 03:01:15 CET 2006

Hi

In my FreeBSD/amd64 box, gpg2 build test fails with a SIGSEGV.

It seems like the same problem as the one reported in last month.
 # http://lists.gnupg.org/pipermail/gnupg-devel/2006-October/023253.html

I attached gdb backtrace below.
Any suggestions?.
