Hi Andrew,

 

I sometimes have a problem with eflex crashing when building with parallel make on Visual Studio 2015.  This is without HOST_OPT=NO to avoid the problem I reported a few minutes ago.

Windows pops up dialog boxes with error as shown in the attachment.

 

When I opened the Visual Studio debugger it reported that the error in eflex was a stack overflow.

 

Note that running make again to pick up where it left off does not fix the problem

I had to go into modules/database/src/ioc, run make clean there, and then go back to the top and run make –sj8 again (without running make clean first).  The second time eflex did not crash.

 

Thanks,
