4 years ago Looks like maybe a deadlock. Since ASAN and TSAN are slower than the usual execution, they are more likely to trigger a deadlock if there is a potential for it. Check out what other threads are doing (in gdb, "thread all apply bt") and most likely you will see that another thread is also stuck while trying to grab a lock.

4 years ago Thanks kcc
thread apply all bt doesn't give any additional information.

4 years ago Sure, it's 'apply all', sorry. If it doesn't show anything, there are no more threads, and a deadlock is unlikely. Another hypothesis: uninitialized mutex? Under asan/tsan the memory is initialized differently than under normal glibc and it may cause a (buggy) code to behave differently. Although it's in libc, which is presumably well tested.
If you can extract a minimal test case (no wx*, no gtk, just pure libc cal to bindtextdomain, I can take a look)

2 years ago I'm encountering the same issue in an entirely unrelated case (software not using wx at all), when trying to run PipeWire or Pulseaudio apps with asan / ubsan: so it seems that the issue is deeper. Also in this case no thread has been created yet so it can't be a "normal" deadlock, but maybe bindtextdomain does not initialize memory properly or something like this...

10 months ago It look like this issue. https://sourceware.org/bugzilla/show_bug.cgi?id=27653
I am experiencing a problem with my c++ application hanging at start when using ASAN or TSAN.
Version Details
Details
If I compile my application with wxWidgets 3.1.3 linked against gtk2 or gtk 3 <= 3.4 then it ASAN and TSAN works correctly. However, if I use gtk >= 3.6 then the application hangs at wxEntry(argc, argv);
This behaviour can be reproduced by using the standard wxWidgets "Hello World" example. (available from https://docs.wxwidgets.org/stable/overview_helloworld.html)
The output of running gdb ./my_test_application is as follows:
The application has hung at _Using host libthread_db library "/lib64/libthreaddb.so.1" Can anybody recommend a fix for this problem?
Kind regards Amanda
