Error with malloc and memory limit

[serman]

HelloI
I am posting here since it could be useful for others too.
(edit: sorry, after submitting, I am realising this message should go to the discussion board)

have received a new version of the model and I found a "random" error related with the outputs.
The model is generated correctly but when I run it I find this error:

After removing some variables form the output.csv file I realized that the problem was not caused by any of them but by having too many. I managed to add the -S ASSERTIONS=1 to the wasm plugin: 

wasmPlugin({ 
emccArgs: [
"-Wall", "-Os ", 
"-sSTRICT=1 ",
 "-sMALLOC=emmalloc", 
"-sFILESYSTEM=0 ",
 "-sMODULARIZE=1 ",
 "-sSINGLE_FILE=1 ", 
"-sEXPORT_ES6=1 ",
 "-sUSE_ES6_IMPORT_META=0 ", 
"-sENVIRONMENT='web,webview,worker' ", 
"-sEXPORTED_FUNCTIONS='_malloc','_free','_getInitialTime','_getFinalTime','_getSaveper','_setLookup','_runModelWithBuffers']", 
"-sEXPORTED_RUNTIME_METHODS=['cwrap']",
 "-sASSERTIONS=1"] }),

(note: I recommend including an example of this in the documentation since I didn't know that -s params don't have a space between "-s XXXXPARAMXXX" I can add it if you want)

And the error I got was:

Which, as suspected, is due to excess memory consumption.
Adding: -sINITIAL_MEMORY=32MB,or -sALLOW_MEMORY_GROWTH=1

seems to fix the problem. 
What do you recommend? Do you think we can get into trouble by using 32MB? It doesn't seem like a lot for an application but I am not familiar with WASM limitations.
