>Environment:
debian unsable (woody) current 7/3/01, 
ALSA and NVdriver additional kernel modules,
default environment setteings,
IA-32 (intel celeron, i440BX chipset, 256MB RAM, 
UDMA (IDE) HD)
>Description:
the code is incorrect, in that ALSAExeption.h:9: should read ALSAException: public std::exception
	but reads:
ALSAException: public exception

hence the parse errors.

However with -ggdb or -ggdb3 the attempt to compile causes an ICE.

-ggdb1 or any -g[1,2,3] don't cause the ICE.

When I avoid the ICE by adding "std::" I get output code that I think is incorect, but that's in another bug report.

>How-To-Repeat:

// to get ICE:
// g++ -fhonor-std -ggdb -c -o ALSAException.o ALSAException.cpp

// I can't get mozilla to attach more than one file, so 
// here is the other part of the problem.
#ifndef AVM_ALSA_EXCEPTION_H
#define AVM_ALSA_EXCEPTION_H

#include <exception>

class ALSAException : public exception
{
public:
  //  ALSAException(char const * const call = "call unspecified.");
  ALSAException(int newErrorNumber, char const * newCall = "call unspecified");
  ALSAException(ALSAException const &);
  virtual ~ALSAException();
  virtual char const * what() const;
  virtual int getErrorNumber() const;
  virtual char const * getCall() const;

private:  
  char* call;
  //  bool const errorNumberValid;
  int errorNumber;
  char* errorNumberText; 
  char* errorNameText; 

};

#endif //AVM_ALSA_EXCEPTION_H


>Fix:
don't use -ggdb or -ggdb3 with -fhonor-std and lack of scope resolution.
