hi, what's this problems?

[wangzhou25]

[trufae]

cant reproduce. can you provide some more details like, the version of frida, the version of ios/android you are testing this? also, i assume you are using the last version of r2 and the last version of r2frida.

to reduce the test coverage, can you verify if reading works when seeking to an aligned address? for example by typing: s..0;x

Another thing you can test is to set the export R2FRIDA_SAFE_IO=1 environment var before launching r2 frida://.. this env var workarounds a bug in frida on android for 32bit.

Thinks for reply, my device type is android 8.1,

I tryed set export R2FRIDA_SAFE_IO=1, it still doesn't work

Please try again with latest r2 and r2frida, i fixed a related issue that was happening on some circunstancies that could be the reason why this was happening.

thanks for reporting! ill close the ticket because this was a well known issue that was partly depending on a bug in Frida and r2frida is now handling it properly
