[DragonFlyBSD - Bug #2395] pkgsrc's intl library segfaults when locking a thread (i386 only)

[John Marino via Redmine <bugtracker-admin@xxxxxxxxxxxxxxxxxxxxx>]

Issue #2395 has been updated by marino.


i believe this is also breaking gconf (though glib2 g_logv) on both pkgsrc and dports.
This really needs to be investigated.

#### DOES NOT AFFECT X86_64, THIS IS I386 ONLY ####

How it was found:
pkgsrc security/libpreludedb wouldn't build, crashed during configuration.
Cause of crash was conftest involving libprelude-config, a program built from security/libprelude.

The program is attached.  It could be built with the following flags:
     cc -o conftest -O2 -g -I/usr/pkg/include -z relro -z now \
      -L/usr/pkg/lib -Wl,-R/usr/pkg/lib -lprelude -lgnutls -lgcrypt -lgpg-error conftest.c

Upon execution, it will segfault with libgcrypt which calls libgpg-error.
libgpg-error, when built with Native Language Support, will invoke bindtextdomain() from libintl (from pkgsrc devel/gettext-lib)
It should be bindtextdomain("libgpg-error", "/usr/pkg/share/locale").
That invocation from gpg-error's init function segfaults when locking a thread.

The backtrace is as follows:

Program received signal SIGSEGV, Segmentation fault.

The problem is problem with pthread library given libintl works on x86_64 and probably every platform supported by pkgsrc.
