Is lin-thread.c and linuxthreads_db essential when debugging multi-threaded program?

[Hyung-Taek Lim]

Hi,

 

I'm sorry. This is not bug report.

 

I found that GDB 5.0 on Linux can debug a multi-threaded program without support of libthread_db.so.

 

I deliberately not loaded libthread_db.so that results in disabling thread_db funcionalities

implemented in lin-thread.c.

 

Then, do I really need thread_db support when debugging multithreaded program in Linux?

Will there be any program that I haven't recognized yet if I use only linux-thread.c and not lin-thread.c in GDB 5.0?

 

Thanks.
