The PathScale Debugger (pathdb) is a component of the PathScale(TM) 
Compiler Suite.  This file describes new features, bugs fixed, and known 
issues with the PathScale Debugger.  Where possible, we provide workarounds
for known problems.

support@pathscale.com.

Version information:
--------------------
The PathScale Debugger (pathdb) version 1.1.1 is a component of the
PathScale Compiler Suite Release 3.1. 

Version 1.1.1 of the debugger contains some fixes to accomodate recent
changes in the debugger information generated by the compiler.

What is new in 1.1:
   * C++ 
      * improved STL printing
      * ability to step over STL generated code
   * Improved EMACS support
   * Better support for Fortran expressions
   * Improved interactive help

Bugs fixed between 1.0 and 1.1:

  [Bug 4943] Disassembly of x87 instructions that store or load values from memory
  [Bug 6611] pathdb writes to stdin?
  [Bug 6694] pathdb dumps core on fc3

Known issues in 1.1:

  [Bug 5055] Commands using Fortran array subscripts
  [Bug 5094] Problems debugging multithreaded applications on older Linux distributions
  [Bug 5477] pathdb will not run if LD_PRELOAD is set

  [Bug 5477] pathdb will not run if LD_PRELOAD is set

    If the environmental variable LD_PRELOAD is set, then pathdb will fail
    to link to the correct libraries.

    Workaround: Do not run pathdb under an LD_PRELOAD variable. If you want
    to debug a program that requires LD_PRELOAD, set LD_PRELOAD from within
    pathdb using the "set environment" command.

  [Bug 5055] Commands using Fortran array subscripts

    The expression handling associated with array subscripts has a number of
    known bugs that are being investigated and fixed. In many cases the user
    may see an "Illegal array index: <value>" message even though the
    subscript is legitimate.

  [Bug 5094] Problems debugging multithreaded applications on older Linux distributions

    The PathScale Debugger makes extensive use of ptrace. On some of the
    older Linux distributions, such as SUSE Linux Enterprise Server v8 (SLES
    8), we are receiving unexpected results from ptrace on multithreaded
    applications. This is being investigated.
