While debugging new code I stumbled over the following observation:
1. fetching a RexxObjectPtr from .local with:
bsfClz=rtc->SendMessage0(rtc->GetLocalEnvironment(), "BSF");
2. getting the string representation (for debugging) of that ooRexx class
object works with:
rtc->CString(rtc->SendMessage0(clzBSF,"STRING"));
3. whereas the following causes a crash:
rtc->CString(rtc->SendMessage0(clzBSF,"MAKESTRING"));
4. whereas the following causes a crash:
const char *str=rtc->ObjectToStringValue(clzBSF);
5. whereas the following causes a crash:
const char *str=rtc->CString(rtc->ObjectToString(clzBSF));
As sending messages to "bsfClz" works reliably, I can proceed with my work,
however, I wonder why
sending "MAKESTRING" or invoking the APIs ObjectToStringValue() and
ObjectToString() in this
scenario might cause a crash in native code?
TIA,
---rony
P.S.: Here's the hs-log file from Java for case # 3, ie. sending MAKESTRING to
"bsfClz";
unfortunately, I have no debug versions of ooRexx available to me and due to
extrem tight time
restrictions only would be able to set that up in about ten days, if necessary,
as I am about to
leave for that time frame:
