Access violation read error

[loumbut5]

Hi, I am trying to build a win32 dynamic library to use in my API but have encountered the following error during run time...

Access violation read to 0x000032EA

I have managed to trace the error back to the file verilated.cpp included in my VC++ 2015 project.

The file was created as part of a Linux freeware called verilator which I have migrated to Windows.

The error occurs in line 237 of the file and my VC++ generates the following warning when running code analysis...

Warning    C6385    Reading invalid data from 'vn':  the readable size is '68' bytes, but '-8' bytes may be read.

The exact code is...

vluint64_t qhat = unw64 / (vluint64_t)(vn[vw-1]);

The problem seems to stem from the term

vn[vw-1]

Please find the file attached and suggest a fix.

Thanks.

Turns out all I had to do was include the line

_assume(vw >= 2);

After line 241 in the code and the warning is fixed.
