If a string-value, which contains parenthesis "()", is passed literally to a user-defined sub:

f. i. testsub("(1)"),

the system obviously gets confused, failing to find the matching pair of parenthesis which enclose the passed arguments (t. i. it wrongly ignores the quotation marks).

One workaround could be using a different pair of characters instead of parenthesis "()", replacing them by parenthesis inside of the user-defined sub and then passing the result to strtoexp.
Braces "{}" or brackets "[]" could be a convenient option, just for a start. If you don't replace these, the result will be enclosed in braces/double brackets "[[...]]", too.

BTW.: I'd call this a bug, too!

There is still a bug related to the usage of the Pi symbol, the 50Hz frequency and the integrative operation!

If you try to calculate the integrative function of a sin (50*<Pi Symbol>*t) between 0.0018 and 0.09, for instance, the calculator takes for ever to return the result.
The problem looks like when the Pi symbol and the 50Hz frequency are used in simultaneous. If we replace the 50Hz by any other value, no matter if the Pi symbol is used or not, the result comes out quite fast. If we replace the Pi symbol for the approximate value of 3.14, no matter what the frequency is, the result also comes quite fast.

I've just updated the OS of my Fx-CP400 to the latest version and the problem remains! :( Not very good for me that I need to make a lot of these kind of calculations!

A new OS version has been released.

Version 2.01.0000

[1] Exam mode
This mode allows you to quickly prepare your calculator for exams.
This mode restricts access to memory, programs,
functions and applications,
so that these features would not be available during exams.

[2] E-CON3 Application
CMA CLAB Data-logger is supported.
E-CON is an application that is used to operate the Data Logger.
CLAB is the Data-logger (collecting the data via light, voltage, temperature sensor, etc) supported by CMA company.

Casio Education Australia says this:
"From June 2016, an OS update is available for the CP 400. It offers a fix for 2D Calculation, Med-Box, Touch Panel Alignment, Logistic Regression and CAS functionality. There is also a data update for Physium."

Looks like the bug is gone. I have updated the OS of 2 calculators and now the calculation of the integral of sin(2*pi*50*t) from 0.0018 up to 0.09 took about 1:40s returning 0.00587067812 and matches WolframAlpha result!
