qemu: uncaught target signal 5 (Trace/breakpoint trap)

[Jolyon]

I'm getting core dumped when running the attached hello binary in qemu, but when using Gdb to remote-debug the program, it exited normally. will appreciate if you can help look into this qemu issue.

And I found that QEMU's 32-bit arm linux-user mode doesn't correctly turn guest BKPT insns into SIGTRAP signal.

0xa602 <_start> movs r0, #22
0xa604 <_start+2> addw r1, pc, #186 ; 0xba
0xa608 <_start+6> bkpt 0x00ab

$readelf -h hello

And I have check that the bug(https://bugs.launchpad.net/qemu/+bug/1873898) is fixed.
But it's coredump.

It seem to can not upload a binary?
