bash core dumping when resize gnome-terminal on amd64

I did some investigation into a core dump of bash that I have been
having.  First, I do not know if this problem exists with the i386 arch,
but it is possible.  I never noticed it.

I use nss_ldap.  There were some efforts to purge shared libraries from
explicitly linking to libthread.so whenever they do not directly use
pthread functions as this can cause issues with the nss layer in libc. 
Some of those issues have been addressed.  Some, unfortunately, are
still around.  I just found a new one:

My openldap, used by nss_ldap, uses sasl.  sasl in turn uses db41.  db41
is building /usr/local/lib/libdb41.so.1 with an explicit link to
libpthread.so.  This is because of line 3263 in dist/configure setting
LDFLAGS to use -lpthread.  This is wrong.  It explicitly links programs
correctly with -lpthread and LDFLAGS is used with creating shared
libraries (don't know why, it really shouldn't as it isn't linking). 
The following patch fixed my core dumps of bash on window resizes:
