src/external/gpl3/gdb/dist/gdb: inf-ptrace.c
Log Message:
Undo previous, it was wrong:
The problem has to do with the threaded initialization.
After we take the first breakpoint and we enter single step mode,
we set trap_expected = 1 in the thread_info structure for main <pid,0,0>.
After the threads initialize, the main thread becomes <pid,1,0>, and so
we get a new thread_info struct with trap_expected = 0, and so we break.
