[Bug] E: runtime error: Pattern count exceeded set limit of '131072' on OSX with ELF Pattern

Mac OSX

What's the issue you encountered?

On OSX (M1 chip) IMHex opening an ELF file causes the ELF pattern to not work

Under the pattern editor we can see the error

E: 726 | struct ELF {
E:              ^^^
E: <Source Code>:745:1
E: 745 | ELF elf @ 0x00;
E:       ^^^


E: runtime error: Pattern count exceeded set limit of '131072'.


E: If this is intended, try increasing the limit using '#pragma pattern_limit <new_limit>'.

Note that manually adding #pragma pattern_limit 10000000 at the top fixes it.

How can the issue be reproduced?

Open a nontrivial ELF file like libcrypto.so.3 from openssl on an OSX machine with IMHex. Try seeing if the ELF pattern works.

ImHex Version

1.33.2

ImHex Build Type

• Nightly or built from sources

Installation type

Additional context?

This is not a bug, as the console clearly states the steps that should be taken to resolve this. This is an intended feature, as we want to limit the amount of patterns to prevent infinite runtime.

@jumanji144 is there a way to set this default globally? So I don't have to edit the pattern every time?

You can save the changes made to any pattern and either overwrite the installed one, given you have permissions to do so, or create your own copy. The one in the installation folder will be overwritten next time you install imhex but the one you save in your own pattern folder will not.
