5.1_RC4 test hang and perl5 configure core dump

["Jeremy C. Reed" <reed%reedmedia.net@localhost>]

(If I should use different mailing list for upcoming 5.1 please let me 
know.)

I upgraded on amd64 (in some virtual machine) from 5.1_RC3 to 5.1_RC4 by 
untarring (with -p) all sets (other than etc) to /usr. Then used 
etcupdate and postinstall to do etc and xetc. Then put the /netbsd in 
place and rebooted. Then I build pkg_install and related with pkgsrc 
bootstrap.

Then attempted to build pbulk and it failed in perl5 configure with:

...
Try to use long doubles if available? [n]  
Checking for optional libraries...
What libraries to use? [-lm -lcrypt -lpthread]  
What optimizer/debugger flag should be used? [  -pthread  
-I/usr/include]  
Any additional cc flags? [-fno-strict-aliasing -pipe -fstack-protector]  
Let me guess what the preprocessor flags are...
Any additional ld flags (NOT including libraries)?
[ -Wl,-rpath,/usr/pkg/lib -Wl,-rpath,/usr/local/lib -fstack-protector]  
Checking your choice of C compiler and flags for coherency...
I've tried to compile and run the following simple program:

#include <stdio.h>
int main() { printf("Ok\n"); return(0); }

I used the command:

        cc -o try -pthread -I/usr/include -fno-strict-aliasing -pipe 
-fstack-protector -Wl,-rpath,/usr/pkg/lib -Wl,-rpath,/usr/local/lib 
-fstack-protector try.c -lm -lcrypt -lpthread
         ./try

and I got the following output:

try: _lwp_ctl: [1]   Segmentation fault (core dumped) ./try
The program compiled OK, but exited with status 139.
You have a problem.  Shall I abort Configure [y]  
Ok.  Stopping Configure.
*** Error code 1

(The "I used" and "I got" above is perl5 not me :)
