[Icenowy]

As I checked, the hash map of dynablocks consists the broken block, which makes the error to happen.

[Icenowy]

after fixing two SIGSEGVs by #172 , there's still SIGSEGV. I will investigate further.

Terraria should works now on box86 (even if latest version are 64bits only now).

Can this ticket be closed?
