Need some help to explain/fix read access violation in C++ code using SaxonC 11.2

Added by Martin Honnen 3 months ago

Hi,

I have tried to integrate SaxonC HE 11.2 into an Notepad++ plugin but get nowhere, any attempt to create Saxon seems to end up with an access violation.

The code to use the SaxonC in the plugin does SaxonProcessor* saxonProc = new SaxonProcessor(); and I get a read access violation in SaxonCGlue.c on line 252 in the function lookForClass on the statement jclass clazz = (*penv)->FindClass(penv, name); where name is shown as 0x00007fffef06c180 "net/sf/saxon/Version" and penv is shown as 0xcdcdcdcdcdcdcdcd {???} in the debugger although the error message says:

Exception thrown: read access violation.
**penv** was 0xFFFFFFFFFFFFFFFF.

I am kind of lost why that is happening, simple console C++ programs using e.g. SaxonProcessor* saxonProc = new SaxonProcessor() work fine.

Thanks for reporting the issue you have found. I have not used the Notepad++ with C++ before, but will investigate it further.

It seems unrelated to Notepad++, in the end even a console app crashes after new SaxonProcessor() without argument, see https://saxonica.plan.io/issues/5429. Will need to test with the new 11.3 release.
