Windows version of Aven 1.2.1 flags "Assertion Failed! ... file gfxcore.cc line 2233 Expression z<=z_ext" on certain .3d files. Pressing "Ignore" button, aven continue and produces a result but I haven't checked if it's correct! "Abort" goes to "Bug in program detected. Please report this to the authors".

On Ubuntu, the same 3d file also fails. There is no assertion failiure dialog box and it goes straight to the "Bug in program..." dialog.

Graham Mullan referred to the Asertion Failure on the Survex list but doesn't seem to have raised a ticket. I have not seen the problem on any of my "real" survey files but found it with the file cave.3d buried in the Therion samples/survex directory. I have reduced this to a single simple file, attached, which reproduces the problem. It's hard to say how serious this is.

Hi, therion uses img.h and img.c, and when I compile and run therion with Undefined Behavior Sanitizer, this error appears:

UndefinedBehaviorSanitizer: undefined-behavior
../extern/img.c:103:27: runtime error: left shift of 255 by 24 places cannot be represented in type 'int'

Problem is in function get32(), where shifting of signed value by 24 bits interferes with a sign bit. Bitwise operations should be done with unsigned types.

Therion CI job where this error occured: ​https://github.com/Afforix/therion/runs/2025117514?check_suite_focus=true.

Would it be possible to define a new command for comments which go across multiple lines. *ref seems to terminate when a new line is made. whereas it might be nice to be able to use a *ref/*endref command to keep the comment within a wrapper.

From my lack of knowledge I think it would be a change to the read_string command ​http://eclipseclp.org/doc/bips/kernel/iochar/read_string-5.html by changing the SepChars? to "*endref".

but then I don't know the first thing about coding, let alone C.
