Unable to get the c stack trace with a corefile from a cgo routine
I'm using https://github.com/gen2brain/aac-go.git to encode AAC in my golang project, but sometimes I got crash in my ARMV7l linux and I have executed like CGO_DEBUG=1 GOTRACEBACK=crash ./binary to got the coredump file, I use gdb-multiarch to view stacktrace but only see stack of golang runtime, it seems c will emit a signal and cgo will handle this signal, so how can I view the exact c calltack of crash, any help will be appreciate.
