***BOGO*** Re: [Mingw-users] GDB and backtrace

[Manuel Martín <mmartin@xxxxxxx>]

More info on my problem.

'Stepping' on gdb I get into a dtor. This is the code:

   pENu::~pENu()
   {
       std::list <lQ*>::iterator iterL;
       iterL = aLiQu->begin();
       while ( iterL != aLiQu->end() )
       {   delete (*iterL);
           iterL = aLiQu->begin();
       }
   }

gdb stops at 'pENu::~pENu()' line and shows lines like these:

Is gcc-4.2.1-2 compiled with -g option?

And 'bt' shows functions I _do_ know can't be called at that point.
And 'info locals' sometimes says "No locals" while really they are:
     std::list <lQ*>::iterator iterL;

I'm getting mad.

TIA
Manolo
