Hi,

I’ve tried running it, getting the following output:

I'm pretty sure the crash is in the error reporting. I only get this text output:

yr4dwpn.asm(31) :

If I correct all errors in the assembly code, HJWasm runs to completion and produces good object files. I'm running in a MS-DOS box under Vista under VMWare under Mac OS X. Perhaps there is less memory available in my setup leading to memory allocation failure.

If I can be of further help, let me know.

Wow that’s quite a nesting of operating systems! :)

We will see if we can find anything specific in the error output that might be memory/allocation dependant.

Would it be possible to try run it under one of the other os levels?

I’ve tried it on my 3 machines now and in a VM and I get constantly the same result, all the errors output until the too many errors.

Sadly, we are not going to be able to get a reproducible case.

I tried on a 64-bit linux system. No problems.

I tried again on my Windows Vista machine. Still crashes. I then asked for it open the debugger to get a call stack trace. Alas, HJWasm32 must be built without symbols, so that proved less than useful. I then downloaded HJWasm source, but could not build it since I have MSVC 2005 and MSVC 2017 does not run on Vista. Oh well.

Then I exited MSVC2005 with the useless stack trace. Now HJWasm32 works! I restarted MSVC and HJWasm32 still works. So now we've determined we can only produce the problem on one machine and on that machine the problem only occurs under certain conditions.

I can only suggest 2 courses of action:

1) Eyeball the error reporting code in hopes of finding a malloc that doesn't check for NULL. 2) Build HJWasm32 with debugging symbols and should the issue recur I can get you a decent stack trace.

john-terraspace commented 7 years ago

I’ve gone through the code and cannot find anything that sticks out as a problem allocation wise.

It might be some sort of C-lib vs. OS issue..

I’ve uploaded a 32bit debug version of HJWasm 2.20 (we’ve just released an updated with a few other minor fixes in) for you.

Thanks for looking into the issue. Should it recur, I'll use the debug version of HJWasm32 to help us find the problem.
