GDB crashed when debugging execve() ... (thread_get_info_callback:cannot get thread info: generic error)

[Neo Jia <cjia at cse dot unl dot edu>]

All,

I am using gdb to debug the JAVA VM. When the function execve() is
invoked, I got the following error messages.

thread_get_info_callback: cannot get thread info: generic error

The following is the procedure I got this error.
