Title:
qemu: uncaught target signal 5 (Trace/breakpoint trap)
Status in QEMU:
Won't Fix
Bug description:
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.
