I'm using WebKitGtk+ with my own JHBuild setting:
https://github.com/tanty/jhbuild-epiphany/tree/wkgtk-devel

Epiphany 3.18.0 and WebKit 2.10.3

I'm running Epiphany with the dconf key:

"process-model" = "shared-secondary-process"

The compilation was done with CMake args:

'-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DDEVELOPER_MODE=ON -DCMAKE_C_FLAGS_DEBUG="-O0 -g1" -DCMAKE_CXX_FLAGS_DEBUG="-O0 -g1"'

When browsing through several web pages, eventually, WebKitWebProcess crashes.

This bug is not reproducible in a predictable way.

WTF::crashUnableToOpenURandom() <-- O_O

Yep! :(

BTW:

root@pomeron:~# ls -lha /dev/urandom
crw-rw-rw- 1 root root 1, 9 Oct 28 12:41 /dev/urandom

So that's fine... it's hard to guess what's wrong, without knowing what the error was....

Just reproduced with similar conditions with WK 2.10.4

Another similar BT from gdb

Same with 2.10.7

The compilation was done with CMake args:

'-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DENABLE_MINIBROWSER=ON -DCMAKE_C_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS"'

I could see in the stderr a lot of messages like:

...

I'm pretty sure the problem is that no new file descriptors can be used, so I'm closing as DUPLICATED from bug 152316
