OOM for huge bytecodes #89

Closed egorvas closed 5 months ago

egorvas commented 5 months ago

Hi, I found that when I using your tool for large bytecodes (fox example like for this address 0x6bd332faf55d7b60096332b3fba3f84b8f601202) it cause error "FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory" I tried to increase memory to 16 gb, but its didn help me. With old implementation of the evm module it works fine. Thanks for any help.

Hi, thanks for sending this. Could you please provide the sevm version where it worked? With this it's easier to find where the problem was introduced.

Sorry, apparently I expressed myself incorrectly. I mean that parsing (for bytecode of this address) works correctly with the original evm module (https://www.npmjs.com/package/evm)

Hi @egorvas, this issue is fixed #94. It is included in the latest release https://github.com/acuarica/evm/releases/tag/v0.6.14. Give it a try!

Just for reference, indeed, the original evm is able to parse the bytecode correctly. However, when trying to decompile it, evm raises the following error

Error: Stack too deep
