Crash when closing window after opening "Flutter Plugins" tab

[nyanpasu64]

I'm running this repo, latest main d385acefcc2405ddb863f79e3ccdb4479891008c, on Linux.

Instructions

• cargo run (both with and without --release).
• Click the "Flutter Plugins" tab.
• Optionally flip tabs. It doesn't matter what tab you're on when you close the program.
• Close the program.

Results (debug)

In a debug build, the program crashes with the following error:

../../third_party/dart/runtime/bin/thread_linux.cc: 248: error: pthread error: 16 (Device or resource busy)
version=2.14.0-228.0.dev (dev) (Sat Jun 19 18:06:49 2021 -0700) on "linux_x64"
fish: Job 1, './target/debug/nativeshell_exam…' terminated by signal SIGSEGV (Address boundary error)

Stack trace (debug)

Apparently when a stack trace includes glib signal connections, GDB renders them out of order and indented. ``` #0 0x00007ffff7c0beb1 in kDartVmSnapshotInstructions () at

Results (release)

In a release build, the program crashes with the following error:

../../third_party/dart/runtime/bin/thread_linux.cc: 248: error: pthread error: 16 (Device or resource busy)
fish: Job 1, './target/release/nativeshell_ex…' terminated by signal SIGABRT (Abort)

The stack trace is basically the same (aside from libflutter_linux_gtk.so being loaded to a different address) except for the top few function calls.
