This seems to be related: andmarti1424/sc-im#364

[ghost]

Confirming - it crashes on all my devices (independently of arch & Android versions).

It looks like problem is not related to opcodes supported by CPU as in #4614 (comment) all expected features are present.

sc-im does not crash under gdb but freezes.

Issue is related to wordexp patches (functions implemented as no-op) - in such case package should be disabled as wordexp is not supported by Bionic libc.

Is this still an issue cause i can get an implementation of wordexp working?

[ghost]

@its-pointless Could you submit patches ?

Fixed in 0.7.0-5.
