[xmlsec] FW: Free/Destroy versus Memory Leak

PostScript ...

   It is not just the verify that leaks. The sign leaks as well. Here is a
very simple signing template. <KeyName> triggers which key to access in
mscrypto store. Everything works fine, it just leaks.

xmlsec sign --crypto mscrypto --repeat 1000 --output

   I tried a few more combinations. It seems to be related to the <KeyName>
element which was used at signing to tell mscrypto what key to use. It is
left over from that original sign activity.

If you take <KeyName> out altogether it still works (probably uses key
directly from X509Certificate) and leaks much less, but it still leaks a
smaller amount.

If it is left in and the <KeyName> exists in crypto store, it goes and gets
it but seems not to free it and it leaks fast.

If it is left in and the <KeyName> does not exist in crypto store, it still
works, and it only leaks a bit.

Hope this helps.

OK, I don't see any leaks on my test... Can you send the files you use in
this run, please?
