I am working on a large-ish codebase containing about 20 libraries. This codebase is currently in PB2017 but we want to migrate it to PB2019R2 in order to benefit from enhanced REST/HTTP support. I have successfully migrated it 2 months ago and started some promising development work on a separate branch, merging from main trunk on a regular basis.
All of sudden, starting Friday we failed to compile the application using either PB environment or command-line pbc2019. We have been trying a lot of different things for the past 3 days but to no avail: Compilation fails and the compiler crashes always in the same place (eg. some resource that's part of the library containing the application program).
I don't know what to do at this stage as PB does not give me any kind of information on why it is failing.
What can I do to investigate that issue? This is critical for us as we are rolling-out new developments and we desparately need that migration to happen.
