--- Comment #4 from Liu Qiang <tcliuqiang at msn dot com> ---
Hello everybody.
I build the powerpc64 crosstoolchain with removing the
'gcc_assert(code==URC_NO_REASON)', and run the new system built by it. The
program (python3 with thread exiting) terminated by SIGSEGV instead of SIGABRT.
Can anyone help?
Program received signal SIGSEGV, Segmentation fault.
