Yes! I have been playing with the memstruct interpreter on 64-bit Linux lately, and I really love having memstructs, but it segfaults when ever I do anything wrong. sad

Like, bad struct passing to C stuff, or crashes in the interpreter itself? I'm sure there are plenty of bugs in there. Porting Win32Lib has been a big help in generating different ways of using them.

There are at least two syntax errors I've been able to produce that result in a Segmentation fault crash.

I think there were a few more but I cannot remember what they were right now, and I have since correct the code that caused them.

I'll surely let you know if they happen again. 

-- segfault when referencing a memstruct within itself. should be "syntax error, 
-- memstruct cannot reference itself directly. did you mean 'pointer TEST_STRUCT next'?" 
 
memstruct TEST_STRUCT 
    TEST_STRUCT next 
end memstruct 

-- segfault when referencing an undefined memtype. should be "memtype 'bool' has not been declared." 
memstruct TEST_STRUCT 
    bool enabled 
end memstruct

Running the latest memstruct branch that I compiled myself recently.
