Description of problem:
I think I have discovered a problem with lesstif for 64bits.

I use a self-compiled version of xmgr (plotting program).
Works fine with FC 11 on 32 bits, but not on 64 bits.
Whenever I do Plot=>Symbols it crashes.

Version-Release number of selected component (if applicable):
Latest FC11 

How reproducible:
Always on 64 bit, never on 32 bit.

Steps to Reproduce:
1.
2.
3.
  
Actual results:

(gdb) run
Starting program: /usr/local/bin/xmgr

Program received signal SIGSEGV, Segmentation fault.

As said this program works fine under 32 bits, so I suspect lesstif rather than xmgr.
