Description Dmitry V. Levin 2003-10-02 04:40:17 EDT
Description of problem: 
This trivial "badly written" pthread test causes "strace -fF" to hang. 
Version-Release number of selected component (if applicable): 
Tested strace-4.4.99 and strace-4.4 
How reproducible: 
Always on all (available for me) linuxthreads platforms. 
Steps to Reproduce: 
gcc -Wall -Werror stracetest.c -lpthread -o stracetest 
strace -fF ./stracetest

Comment 2 Roland McGrath 2003-11-06 21:13:37 EST
I cannot reproduce this in 4.4.99-1.  Please verify the strace, glibc,
and kernel versions you are using.
Comment 3 Dmitry V. Levin 2003-11-07 08:24:28 EST
As I wrote in original post before bugzilla corruption, 
tested with 
kernel-2.2.25 and kernel-2.4.22, 
glibc-2.2.5 and glibc-2.3.2, 
on few ALT Linux and Debian distributions. 
All above with linuxthreads.

Comment 5 Dmitry V. Levin 2003-12-14 18:40:57 EST
Apparently fixed in strace-4.5.1 (linuxthreads bug?); 
your patch which fixes the problem is attached for convenience.
