interpreter crashes at tooldata_find_index_for_tool was created by Reinhard
Hi,
I try to internally use the interpreter in a Qt-app and I hope, that it will be faster, than parsing text output from interpreter on my own.
As always I try to follow axis code ...
I use qtcreator with debugger to narrow the problem. In the loop of read/execute crash happens at execute with this stack-trace:
For check I run axis with the same config/gcode-file and there's no problem.
In my java-app I use the ready compiled interpreter-executable, so I tried that too and got some strange result. I call the interpreter with "rs274 -g -v [var-file] -i [ini-file] -t [tool-table] -n 0 -l 999 2> error.log > log"
Here's the log:... and these are the errors:
Axis or backend don't report any errors using same files.

Replied by Reinhard on topic interpreter crashes at tooldata_find_index_for_tool
Hi,
I got a bit further with testing. My prototype for testing is available
With that prototype I can compare internal and external interpreter usage. When I use an oldstyle rip installation (with configure --enable-toolnml) everything works fine. Same is true, if external interpreter is used.
With a new style rip installation interpreter crashes with above stacktrace.
This crash is reproducible using sample gcode file from linuxcnc: gmoccapy_2_tools_with_cutter_radius_compensation.ngc
It seems, that tooldata_find_index_for_tool lacks some check for valid tool_mmap_base.
*hptr is NULL.
I don't know, whether I should have initialized that in my app.
So I'm asking for help.
