Is that on Windows? I never had problems like that in the release
version, but I use IDL in Linux nearly all the time.

I experienced this "fragility" several times when developing code by
using the IDL8 Workbench. Typically, if a program is run at the main
level and get some error, it stops but in "resume" state (like with
any breakpoint). I can modify the code, then resume the program. That
is in general o.k. except, I guess, when some lines have been added or
suppressed in the corrected code. In this case IDL crashes silently
(note that, in Windows, the Java runtime log file reports an access
violation in idl.dll). The sequence run-error-correct-resume is new
with IDL8: in older version, you should reset and restart the program.
I do not know if it is a bug or a feature...
alx.
