IDA crashes after analyzing firmware sample with efiXplorer latest builds

[3vangel1st]

Hi, I'm using IDA Pro 7.7 with SDK 7.7 (on Windows) and used your latest builds to install. When loading this firmware sample from Asus: https://github.com/3vangel1st/FWare/blob/main/X515JAAS.306 , I do see it gets loaded. When starting the efiXplorer plugin from the menu, I click through the pop-ups and it starts running and doing some analysis. However it never completes since after a while IDA crashes and generates a mini-dump.

Any idea what possibly is going wrong? I admit this is the only firmware sample I've used so far ;)

Hi. I just checked. Can not reproduce this issue. It's working fine for me:

If you are using IDA without a Hex-Rays decompiler, it is best to build the plugin from master with Hex-Rays analysis disabled. I'll PM you to clarify some details.

[3vangel1st]

Understood - don't have the Hex-Rays decompiler.

@yeggor could you please fix the code to not invoke decompiler APIs if the decompiler is not present (e.g. init_hexrays_plugin() returned false)? We're getting crash reports from customers because the plugin calls nullptr.

@skochinsky thank you. It fixed now

I've tested it on x86 and arm EFI modules. Works without problems now. Sorry for the inconvenience.
