NULL pointer exception #43

Closed pdamian closed 1 year ago

pdamian commented 1 year ago

I get a NULL pointer exception when having the plugin installed, and opening a binary in the Ghidra code browser:

Cannot invoke "ghidra.program.model.mem.MemoryBlock.getName()" because the return value of "ghidra.program.model.mem.Memory.getBlock(ghidra.program.model.address.Address)" is null
java.lang.NullPointerException: Cannot invoke "ghidra.program.model.mem.MemoryBlock.getName()" because the return value of "ghidra.program.model.mem.Memory.getBlock(ghidra.program.model.address.Address)" is null
