Fatal signal 11 (SIGSEGV), code 1, from libssl.so (SSL_shutdown+158)

[diousk]

Hi,

I found that our production app sometimes crashed from native library libssl.so (SSL_shutdown+158)
Can you help check this?

Device: Google Pixel
OS: Android 8.0.0
OkHttp version: 3.8.1
Retrofit version: 2.3.0

crash log:

Thanks.

@kruton ideas?

@diousk is this still reproducible? And have you seen it on other devices?

I'm tempted to close as it seems like out of scope for OkHttp to cause or fix this issue.

Closing as we aren't seeing other reports, and it's potentially just a bug in 8.0 that could be fixed in later android versions.
