Any chance that the string in g.tempStr is not null terminated? StrNCopy
does not null terminate if StrLen(msg) > MAX_TEMP_STR

Subject: Re: FrmCustomAlert causes crash
Jeffrey,
I'm getting a similar problem with FrmCustomAlert - but I'm sure my strings
are less than 100 bytes.
Running gremlins, my standard procedure for reporting text messages to the
user is exercised thousands of times.
But after 689,000 odd iterations I get "Read from unallocated chunk of
memory" or similar.
Pose version is 3.0a3, device emulated is Palm IIIx
Code follows:
++++++++++++++++++++++++++
Boolean alertMsg(
Word id,
int code)
{
VoidHand resHdl = DmGetResource('tSTR', code);
if (resHdl != NULL) {
VoidPtr msg = lockMemory(resHdl, "alertMsg", true);
if (msg != NULL) {
StrNCopy(g.tempStr, msg, MAX_TEMP_STR);
if (FrmCustomAlert (id, g.tempStr, " ", " ") == 0)
{
unlockMemory(resHdl, "alertMsg", true);
return true;
}
}
}
unlockMemory(resHdl, "alertMsg", true);
return false;
}
++++++++++++++++++++++++++++++++++
Do you think this may be the same error???
Please let me know if you produce a fix/workaround
