deleting a void* is not defined
Hi,
I am working with the current version of the Axis C++ trunk and I see
this warning when I compile on Linux with gcc 3.4.4
[cc] 120 total files to be compiled.
[cc]
/usr/local/tmp/emanuel/BUILD/ws-axis/obj/src/common/ArrayBean.cpp: In
destructor `virtual axiscpp::ArrayBean::~ArrayBean()':
[cc]
/usr/local/tmp/emanuel/BUILD/ws-axis/obj/src/common/ArrayBean.cpp:329:
warning: deleting `void*' is undefined
When I did a google search for "C++ delete void*" I found that the consensus
was that deleting a void* is a no-no in C++.
I also remember valgrind complaining about this when I ran it for memory
leak checking.
The problem is on line 329 in ArrayBean.cpp with the following code:
delete [] m_value.sta;
It seems that the ArrayBean class (judging from the switch statement
above this)
knows the actual type of m_value.sta. Would it be feasable to introduce
another
switch statement which casts m_value.sta to the correct type before
deleting it?
Since I am not that familiar with the code maybe the issue is more
complicated than
that or this may be a non-issue, but I can try it if you want to.
The reason I want to use the latest version of Axis C++ is that I am
experiencing
crashes on Solaris when running the same code that I run on Linux
without any problems,
but so far I have not tried it on the latest version.
/Cheers
Emanuel

Emanuel,
Since we are deleting an array of pointers, the way this is coded is OK.
There are no destructors to call. The delete will release the storage by
calling the global ::operator delete[]()...I guess you compiler or C++
runtime does not do that.
How about trying
delete [] (void **)m_value.sta;
Does that work? If not, I can change to
delete [] (char **)m_value.sta;
Kind of a hack....until this is cleared up.
