Hi,
I am using g++ version 2.95.2. The following code crashes
intermittently
typedef unsigned char BYTE;
int nNewSize = 1;
void** m_pData = ( void ** ) new BYTE[ nNewSize * sizeof( BYTE *
) ];
Back trace on gdb does not give me the lib where it crashes
Then, I tried this,
void** m_pData = ( void ** )malloc( nNewSize * sizeof(
void * ) );
and even
void** m_pData = ( void ** )malloc( 4 );
But it always gives a SIGSEGV. bt from gdb in this case gives
#0 in _smalloc() from /usr/lib/libc.so.1
#1 in malloc() from /usr/lib/libc.so.1
What am I doing wrong? Have I run out of virtual memory for malloc to
crash?
TIA,
Kartik
