Also, the GNU zip utilities (gzip, gunzip, gzcat) just hang (in state
"parked") when run on aarch64 after the above commit.  Reverting it lets
them work correctly again.

(Noticed while installing an upgrade - the upgrade stopped progressing

Does it work if you just revert this:

Modified Files:
src/lib/libpthread: pthread.c pthread_int.h pthread_mutex.c
pthread_tsd.c

Log Message:
Enhance the pthread(3) + malloc(3) init model

Separate the pthread_atfork(3) call from pthread_tsd_init()
and move it into a distinct function.

Call inside pthread__init() late TSD initialization route, just after
"pthread_atfork(NULL, NULL, pthread__fork_callback);".

Document that malloc(3) initialization is now controlled again and called
during the first pthread_atfork(3) call.

Remove #if 0 code from pthread_mutex.c as we no longer initialize malloc
prematurely.

mpv coredump

2020-02-16 Thread Thomas Klausner 
Hi!

I've upgraded kernel + userland to 9.99.47/amd64.
Now mpv (built on 9.99.43) dumps core immediately.

Core was generated by `mpv'.
Program terminated with signal SIGSEGV, Segmentation fault.
