i am using musl libc cross-toolchain, did this matter for this?

[msisov]

maybe. Can you use gdb server and attach a remote debugger to get a meaningful backtrace?

[13824125580]

@msisov, below is the gdb dump output, so can you give me some hints about this?
thank you.

meta-browser (i.e. this github repository) doesn't support musl.

[kraj]

in this case the sources are not being prepared from meta-browser recipe it seems. So musl-cross toolchain is a separate cross SDK then yocto/OE, its possible that target system is running OE, so as such I dont think this question is relevant to OE directly. However, at one point we had chromium-x11 and firefox both functional with musl, but since community wasn't testing it as much it kind of has regressed, it should be resurrected so I am interested in all the patches that you are carrying for musl support and you might go back in meta-browser history to see all the patches that we once had for these browsers to work with musl.

thanks you all.
