[aspectc-user] Segmentation fault parsing a C++ header file

[jorgefm at cirsa.com]

Hello,

I've recently updated my system to Mandriva 2006, and then I've update my
AspectC++
from 0.9.1 to 1.0pre1. Mainly, I only use the Puma library to parse some
headers files to
generate a custom CORBA idl files. With the old version it was working ok,
but now I
get segmentation faults parsing the files.

I've tested the ccparser from the Puma/examples/ccparser directory with the
same
result.

My test header file to parse is:

// == IXaviText.h  ==== 8< ==================

#ifndef __ITEST_H_
#define __ITEST_H_

typedef struct
{
   char     test1;
   char     test2;
   char     test3;
   char     test4;
   char     test5;
} TCrbi18nRepresentation;

class IXaviTest
{
public:
  virtual ~IXaviTest(){};
  virtual bool GetBasicRepresentation( const char * country, const char *
lang, TCrbi18nRepresentation * repr ) = 0;
  virtual bool SetBasicRepresentation( const char * country, const char *
lang, TCrbi18nRepresentation repr ) = 0;
};

#endif

// ==== 8< ==================

Then I set my environment to generate core dumps when a segmentation fault
occurs:


$ ulimit -c unlimited

$ ./ccparser IXaviTest.h
Starting parse process...
Segmentation fault (core dumped)

$ gdb ./ccparser core.25204
