compiler coredump on single-quote #111

Closed rchowinfoblox closed 3 years ago

rchowinfoblox commented 3 years ago

This SEAL with single-quote instead of double-quote causes compiler segfault:

allow subject group everyone to manage rchow.abacpolicy where ctx.id == 'deadbeef'

coredump:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x77c45a]
