Re: [Swftools-common] SWFC crashes encountered on Linux

[WU Liang]

Sorry that I missed something important:

First I suspected that there is something wrong with the C lib function strlen().

Then I wrote a small C program to read in the whole script file, put it in a string and checked if it would crash using strlen().

Fortunately, it didnot.

 

So I decided that there may be something wrong with the code in SWFC.

Maybe it's because of the preprocessing of the script file, maybe.

 

Besides, not only the strlen() but also the printf() function would crash in the readToken().

The printf() didnot cause the small C program to crash either.

 

Thanks,

Liang

It's working for me, it didn't crash with 3096+ vars Maybe it's worth to check your environment limits with:

ulimit -a

This is the output of my laptop, for you to compare with yours:

address@hidden:~$ ulimit -a
