Hello,
Is max-lisp-eval-depth what you are looking for?
max-lisp-eval-depth is a variable defined in ‘C source code’.
Its value is 800
This variable may be risky if used as a file-local variable.
Documentation:
Limit on depth in ‘eval’, ‘apply’ and ‘funcall’ before error.
This limit serves to catch infinite recursions for you before they cause
actual stack overflow in C, which would be fatal for Emacs.
You can safely make it considerably larger than its default value,
if that proves inconveniently small. However, if you increase it too far,
Emacs could overflow the real C stack, and crash.
Regards,
Rhys

Hello again,
I’ve been watching progress in development around this
Mac/Emacs/MATLAB issue. They have identified that the reason MATLAB
is crashing in Emacs, but not on the command line is because Emacs is
setting the stack size. A way to reproduce outside of Emacs is as
follows:
ulimit -s 8515
matlab
Stacks limited to sizes of 8512 or more works fine for them.
I looked into stack size within emacs, and saw several references to
increasing the stack size to 8519 in Emacs to work around a bug I’m
not familiar with, but not to a way to increase the stack size of
sub-processes.
Any Emacs hackers on this list familiar with updating stack size for
sub-processes in Emacs as a way to work around this problem?
Thanks
Eric

matlab R2016b on Mac OS 10.11.6 Emacs 25.1
Further evidence (I hope this helps someone solve the problem):
1. 2016b works in NONE of the emacs terminals: shell, term or e-shell.
2. 2016b works fine (even with -nodesktop) from Xquartz's xterm or
OSX's terminal
3. 2016a works fine in emacs
4. Running diff on the java directories (where the potentially
offending files reside) shows NO difference between 2016a and 2016b!
$ diff -ur /Applications/MATLAB_R2016b.app/sys/java
/Applications/MATLAB_R2016a.app/sys/java
This might not be a Java issue.

Yes, I'm seeing this problem, too. Mathworks won't touch it, as
it does seem to be a real third party issue with Emacs.
I'm having the problem with OSX 10.12 and Emacs 25.1.1, although
it was also present with my previous emacs (24.5?).
I checked the environment variables, and the only thing I see
significantly different is that emacs shell reports as TERM=dumb,
while the Xquartz one is TERM=xterm and apple's terminal is
TERM=xterm-256color.
In all cases, the actual shell is /bin/bash. I'm guessing this
has something to do with how emacs is setting up the shell, but I
can't figure out what the issue is, exactly. May be time to cross
post to emacs developers.
