Upgrading 32-bit Mac apps to 64-bit

I am using a MacBook Pro running macOS Sierra Version 10.12.4 to upgrade my first six 32-bits Mac apps to 64-bits.

Each of the six apps worked fine when compiled for 32-bits.

Because my Mac Xojo license expired late last year, I used Xojo 2017 Release 1.1 to test the apps in the IDE for 64-bits and then compiled them for 64-bits using Xojo 2016 Release 3.

Launching each app twenty times, I recorded an exception upon close 20% to 50% of the time.

The Console log shows: “Service exited dur to signal: Segmentation fault: 11 sent by exc handler (0).

Can someone tell me in simple English what this means?

Thanks in advance.
