There is if you use -rdynamic and -g. Incidentally, this may cause
normal core dumps to provide less or different info. Here is a basic
sample of a stack frame print function, which is probably specific to
linux:
#include
#include
void show_stackframe()
{
void* trace[ 64 ];
char** messages = NULL;
int trace_size = 0;
cerr << "Begin Stack Frame Dump" << endl;
cerr << "(if useful symbols are not found, try recompiling "
<< "with -rdynamic during link, and -g without -O#)"
<< endl;
trace_size = backtrace( trace, 64 );
messages = backtrace_symbols( trace, trace_size );
for( int i = 0; i < trace_size; ++i ) {
cerr << "Traced: " << messages[i] << endl;
}
cerr << "End Stack Frame Dump" << endl;
}
I've used this at times to debug asyncronous code and figure out what
had been called from where, I actually keep a commented out version in
my game code.
