i have a complete client. i actually tried a few of them. Instant
client and the one delivered with oracle XE both include a dll
(OCI.dll) which depends on the wrong version of the miscrosoft
runtime library, and cause random failures of my application, when an
object allocated by the old runtime gets freed in the new runtime. My
application builds and runs most of the time but random crashes are a
show stopper.

Thats why you don't allocate memory in one module and deallocate it in
another.

this is hard to do when a library returns a pointer to an object it
has allocated for you.


Brrrr. :-) Well, maybe you can create a simple wrapper dll that links
to the same dll as the OCI.dll and supplies a ociFree(void*);
function, that just calls free() so that the correct one is used ...

If the OCI.dll needs this, then it's a crappy interface. (Yes, I know,
not very helpful here, sorry.)
Maybe you can come up with a workaround where the memory stuff is kept
to each module.

working around stupid APIs is becoming the main part of my job since
the powers that be decided microsoft and oracle were the way to go.


Well. If it'd be simple everyone could do it ... ;-)

good luck!
