    runtime: print user stack on other threads during GOTRACBEACK=crash · 4b8f41da
    Austin Clements authored
    Currently, when printing tracebacks of other threads during
    GOTRACEBACK=crash, if the thread is on the system stack we print only
    the header for the user goroutine and fail to print its stack. This
    happens because we passed the g0 to traceback instead of curg. The g0
    never has anything set in its gobuf, so traceback doesn't print
    anything.
    
    Fix this by passing _g_.m.curg to traceback instead of the g0.
    
    Fixes #19494.
