[Paracomp-users] Paracomp crash when compiled in release mode

[Shree K. <shr...@hp...>]

Hi James,

I ran into the same problem which you faced : crash when paracomp is
compiled in release mode.

My system : an x86_64 machine running Fedora Core 8(x86_64). GCC version
4.1.2

Basically, any program using the library crashes, _if_ paracomp was
compiled in release mode. If paracomp is compiled in debug mode
"release=0" things move just fine.

I investigated this a bit, and found that a dlclose() in
loadCompositePlugin() (pcimpl.cpp) is causing the crash.

 using namespace paracomp;

        // if the init function returns non-zero, then it cannot be used
        if(((*initFunc)())!=0)
        {
-               dlclose(libHandle);
+             //dlclose(libHandle); // commenting this out gets rid of
the crash
                return false;
        }
----------------------------------------------------------

Seems to be a compiler related issue, since I don't see this on our RHEL
5 based system (running GCC 3.4.6). 

James, do you remember what compiler version you saw the issue on ?

For now, I don't have a solution. Commenting out gets rid of the
problem. This will result in a small memory leak, but should be good to
keep people going.

Just something I thought everybody must know before we find a solution
to the problem.
