 In reference to bug #1407 in gdb-gnats:
 
 I pulled the CVS branch as specified in a response to the original bug
 report and it does not appear to fix the problem.
 
 The test case is really simple:
 
 int foo(void)
 {
     return 1;
 }
  
 int main(void)
 {
     foo();
     return 1;
 }
 
 
 The compiler and gdb versions:
 
 zodiac:~ > gcc -v

 Configured with: ./configure --prefix=/usr/local
 --enable-languages=c,c++,ada,f77,obj --disable-nls --enable-system-zlib
 --enable-threads

 (gdb) call foo()
  
 Program received signal SIGSEGV, Segmentation fault.
 <function called from gdb>
 The program being debugged was signaled while in a function called from
 GDB.
 GDB remains in the frame where the signal was received.
 To change this behavior use "set unwindonsignal on"
 Evaluation of the expression containing the function (foo) will be
 abandoned.
 (gdb) quit
 The program is running.  Exit anyway? (y or n) y
 
 
 Any input you could offer would be appreciated.  Thank You.
