From today's MacFixIt:
Script Debugger bug reveals Mac OS X 10.2.x AppleScript flaw Under Mac OS X
10.2.x, Script Debugger fails to compile large scripts. When attempting to
compile scripts over 3000 lines, the program will return an "out of memory
error." Mark Aldritt of Late Night Software (creators of Script Debugger)
says the bug is actually a reflection on flaws in the AppleScript
implementation, that are simply reported more accurately in Mac OS X 10.2.x:
"It turns out that there is a long standing bug in AppleScript involving
the loading of scripts whose source code contains more than 32765 style
runs (fonts, styles, colors, etc). When this limit is exceeded, AppleScript
attempts to allocate a large (> 2GB) block of memory which fails even under
Mac OS X. AppleScript versions prior to 1.9 would fail silently and proceed
to write into invalid memory addresses. With the advent (of) AppleScript
1.9, the failed memory allocation is now detected and the out of memory
error is reported from AppleScript through Script Debugger to you.
"I understand from Apple that they will be resolving the underlying problem
in the next AppleScript release. Unfortunately, we have not been able to
identify a way of working around this AppleScript bug from our end so we
must wait for Apple to resolve the issue.
"We recognize that this is a serious problem and we are deeply frustrated
with the situation."
