Dear FSF people:

My system is Sun3/60 with OS3.4, gdb-3.1, and gcc-1.34.  'finish' command
doesn't work fine in some situation (it is ok in gdb-2.8.1).

The example program and shell logging record are appended to the last of this
letter.

Please try to set breakpoint at the function 'bar' and run program.  When
progrm stops at the head of 'bar', invoke finish.

----------beginning of example program----------------
#include	<stdio.h>

typedef enum { ok, error } e_fv;

e_fv
bar()
{
   return error;
}

void
foo()
{
   if (bar() != ok)
      (void)printf("error");
}

void
main()
{
   foo();
}
--------end of example program-------------------------
