How to get a full description of a given bugid ?

Question

Hello there,
we got a crash on our software since the installation of the february patch cluster. The stack shows that the process crash when calling ex_clean function.
The problem occurs on solaris 8 and 9 and I wonder if this problem is not linked with the fix of bug id 6326163
(extract from 108434-21 patch release notes)
6326163 C++ exception propagates outside of destructor, while "stack unwinding"
Is it possible to get more information regarding this bugid 6326163

Answer 1

Regarding the support contract, we should probably have some, I must investigate.
Regarding my ex_clean problem, I could reproduce the problem with the latest compiler patch installed
Here is the program I compiled with :
% CC -V
CC: Sun C++ 5.8 Patch 121017-01 2005/12/11
%CC -mt -c test.cpp
%CC -o test test.o -lpthread -R /usr/lib/lwp
===========================================
#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
void Die(const char* what)
printf("Die %s\n");
exit(1);
class TryCatchThread
public:
pthread_t fThread;
void Start();
void ThreadFunction();
void Join();
extern "C" void* ThreadEntryPoint(void *thread)
((TryCatchThread*)thread)->ThreadFunction();
return NULL;
void TryCatchThread::Start()
if ( pthread_create(&fThread, NULL, ThreadEntryPoint, this) ) Die("pthread_create");
void TryCatchThread::ThreadFunction()
printf("[%hd] Entering thread function\n", fThread);
for(int i=0; i<100000; i++)
try { throw("level1"); }
catch(const char*)
try { throw("level2"); }
catch(const char*) { }
printf("[%hd] Leaving thread function\n", fThread);
void TryCatchThread::Join()
void *val;
if ( pthread_join(fThread, &val) ) Die("pthread_join");
int main(int argc, char* argv[])
unsigned long i=0;
while(1)
printf("%u\n", i);
TryCatchThread t1; t1.Start();
TryCatchThread t2; t2.Start();
TryCatchThread t3; t3.Start();
TryCatchThread t4; t4.Start();
t1.Join();
t2.Join();
t3.Join();
t4.Join();
i++;
===========================================
After few seconds, it dumps a core with ex_clean pstack :

The compiled program works fine on a sun with old runtime (108434-18)
and it failed on another sun with newer (108434-20) and latest runtime (108434-21) installed. Regression bug or do I miss something ?
