Synopsis: Gcc [ throw generate core dump ( TRU64 5.1 ) ]
State-Changed-From-To: open->closed
State-Changed-By: pme
State-Changed-When: Fri Sep 27 09:30:17 2002
State-Changed-Why:
This is not a bug. (The Sun compiler is wrong.) You are
throwing a string literal, which has type "const char *".
You are catching only "char *". Therefore the exception
is not caught, and propogates off the stack, which calls
terminate(), which calls abort(), which dumps core.
Change the catch line to "catch (const char * str)"
instead.

throw generate a core dump.
Our code run uccefully under a Sun machine.
We use gcc on SUN with the same build options.
>How-To-Repeat:
On Dec machine:
Build the sample code and run it.
// #include <stdio.h>
class toto
{
public:
void printout(char * s );
};
void toto::printout( char * s )
{
// printf("Hello from printout\n");
throw "throw from printout";
}
int main()
{
char *buf;
toto t;
try
{
buf = new char[512];
// throw ("Memory allocation failure!");
t.printout("Hello");
}
catch( char * str )
{
// printf("Exception raised: %s\n",str );
}
// ...
return 0;
}
