It's an access violation:
First chance exception at $00000051. Exception class $C0000005 with message 'access violation at 0x00000051: read of address 0x00000051'. Process bds.exe (8896)

(Found that by running the IDE in the debugger without debug info in GExperts.)

Idea: Only compile the classs browser units with debug information and try to run that in the debugger.
