Re: dlopen error

I meant that on the machine where you have the dlopen is failing the current directory ('.') is not listed in the variable LD_LIBRARY_PATH (it is usually added in the user's .cshrc or .bashrc). It is usually *not* recommended to have '.' listed in the LD_LIBRARY_PATH (for security reasons as it provides a vector for intrusions). The alternative is to have the directory (/tmp/bawa/macros/) listed explicitly in the LD_LIBRARY_PATH.

As pointed in a different mail, valgrind points out that you code is using an histogram pointer after it has been deleted (by closing the file it belongs to).

Cheers,
Philippe.
