Title:
Crash caused by exception thown from
DMABufTextureBinder::ensure_egl_image()
Status in Mir:
New
Status in mir package in Ubuntu:
New
Bug description:
The most reliable way I have to reproduce is:
1. Run (Mir-on-X) $ miral-shell --window-manager tiling
2. Run a script that iterates over mir_demo_client_* launching all our demo
clients.
The following exception causes a segfault in report_exception() -
because by then the library has been unloaded:
