Subject: Why  GCC/ GDB ignore a normal C  statement?
Date: Mon, 05 May 2003 11:32:00 -0000	[thread overview]
Message-ID: <20030505113250.55949.qmail@web20709.mail.yahoo.com> (raw)

Hi:

As a beginner of linux programming, I am learning to
recompile and rebuild my previous programs in Linux
with GCC/GDB.   However, there is something really
annoying me.  The code is showed as :

if ( ( d_z - current ) < MIN_ERROR && ( d_z - current
) > -MIN_ERROR)
		{
			d_z += dz_inc; 
			mp += mstep_k; 
			i_cz += step_k;			
			offset+= mstep_k;
		}
some graphical front-ends of GDB like GVD show that
the statement 

i_cz +=step_k; 

is NOT recongnised as a  statement.  The GDB just
simpily ignores it when stepping to there.   This
means the varible i_cz,which is declared as a register
int varible,  has not  updated after executing.  The
contexts work well and this part of code runs
perfectlly when compiled with VC in Windows.

Could someone give me an idea about this problem?  I
would be very grateful...

Frank Zhao
