Installing 11.5 over CR9 breaks parameter passing? (strings with digits)

Question

This is soo very weird. Our app uses CR9 and there has generally not been a problem with customers running it in parallell with more recent versions of CR, until this. I got a report from a client that certain reports would crash with a general protection. It was absolutely impossible to duplicate, until I installed the same bookkeeping app, an app that apparently installs Enterprise 11.5.
After that, passing a parameter (m_Report->ParameterFields->GetItemByName(itemName)->AddCurrentValue(itemValue);) will crash, but only, and only if the string has a digit somewhere in the beginning, say the first 10 or so positions??
Ie, I can pass: "blablabla blabla blablabla1", but not "1blabla" or even "blabla1blabla"

Answer 1

Thanks for your quick answer!
For initial testing, I only had the actual 3rd party app that updated CR, but I then created a virgin Xp under VMWare, then tried installing both Xi (As we have Xi in house, but when we upgraded our deveoper system bought it with the option to use CR9) and the CR 12 runtime. Then installed our own (CR9) app. I was not able to duplicate the problem with those two setups, so I assume that the problem must lie in some of the DLLs shipped with that "other" app or with the way they install it.
I have emailed the vendor asking for more info and I will also run a snapshot of their install to try to find out what files they replace.
Even if we have stayed with CR9, we have seen very little problems with customers who have other versions of CR and the reason for us staying with CR9 is because another vendor (A banking app) that most of are clients use are also on CR9 and have no plans to upgrade.
I realise that the problem might not be with CR at all, but it was just so weird (ie a numeric within the start of a string) that I posted here in the hope that someone else might have seen it.
