GNU libstdc++ crash 64 bits gcc 3.4.2

[faria]

Hi,

I would like if somedy has had problem with GNU libstdc++ with 64 bits
?

Sometimes I have got a bus error at libstdc++ with gcc 3.4.2
in SUN.

I have used a multithread 64 bits application that loads dynamicly ( as
a application's plugin ) a couple of dinamic libraries. That
application and all your dynamic libraries have a strong use of C++
Standard Librarie.

Sometimes, when the application is running over high load
It has received a bus error. The error is got in the push_back() method
call to a vector object.
I have a limited stack trace got using "mdb" ( see below ), because I
was not able to reproduce the error in development.

I would like know if the error could is or due some libstdc++ bug
either some missing compilation flag ( i have used -fPIC -shared -m64
in shared libraries generation ), either some application bug.

Could somebody gives me any hint/tip ? Below is the stack trace.

Thank you,

Frederico Faria

Information about the environment
The application is compiled with:
SunOS 5.8 Generic_117350-04 sun4u sparc SUNW,Sun-Fire-V210
GCC 3.4.2

The application runs another SUN:
SunOS 5.9 Generic_118558-04 sun4u sparc SUNW,Sun-Fire-880

A bit of schadenfreude, eh? ;-)

You should post in a g++ group since this is a platform-specific
question. See the FAQ for what is on-topic here and for some
suggestions of better groups to post in:

Maybe a newer version of gcc (like 4.x) should help ?

Trying a different STL might be worth a shot to isolate the problem.
STLPort is pretty good.

Is your compiler built with the -enable-threads option?
Run "g++ -v" to find out.
