BLAST fails if the LDV_ERROR label and ldv_main are defined in different files
This is a lie.

Awful truth :)
Rising to High because Small test set fails and prevents pushing new version of envgen into master

Vadim, please, create a couple of source code files (or check the ones I've attached) and stop insisting on an issue that has nothing to do with the problem.

That's not "High", that's "Immediate". I'll address these bugs today.

The issue is that there is an error, and I'm not insisting that the cause is main and label placed in different files. On such examples BLAST has worked before and is working now even in small tests. Moreover, I suspect that the error caused by recent changes in envgen. The title just describes the example tests-envgen-test-twomains-mutex and it is not a lie :) I changed it to be the truth.

I found the issue. The thing is that BLAST indeed doesn't find the main you specified (ldv_main1_plain_sorted_withcheck).
But this main does present in main_2.obj.i file! What's the matter?
When parsing this function, CIL found that the label ldv_module_exit was "goto-ed" but was not specified. This led to "Error" at 111th line, as you can see in the trace you attached. The possible consequence of this is that BLAST didn't add the function to the "global function table", and thus it wasn't found during the entry point lookup. Hence the error.
The bug about this incorrect way of generating the model is #422.
