一个CGO的问题

写了个CGO的调用，用到了crypto这个库，但是程序有时候会正常运行，有时候又会崩溃，都是在同一个地方崩溃。崩溃的情况下报了这个错误： fatal error: unexpected signal during runtime execution [signal 0xb code=0x1 addr=0xfffffffff80011c0 pc=0x3dd1c6a437] runtime stack: runtime.gothrow(0x6fd250, 0x2a) /usr/local/go/src/runtime/panic.go:503 +0x8e runtime.sigpanic() /usr/local/go/src/runtime/sigpanic_unix.go:14 +0x5e goroutine 1 [syscall, locked to thread]: runtime.cgocall_errno(0x401a30, 0xc20807ada0, 0x0) /usr/local/go/src/runtime/cgocall.go:130 +0xf5 fp=0xc20807ad80 sp=0xc20807ad58 mendicant/check._Cfunc_check_sign(0x7f80f80008c0, 0x7f80f8000a30, 0x7f80000000ae, 0xc200000000) mendicant/check/_obj/_cgo_gotypes.go:34 +0x43 fp=0xc20807ada0 sp=0xc20807ad80 mendicant/check.CheckModule() /home/csy/goitem/src/mendicant/check/check.go:54 +0xaae fp=0xc20807af78 sp=0xc20807ada0 main.Test_Check() /home/csy/goitem/src/mendicant/test/testmain.go:28 +0x1b fp=0xc20807af80 sp=0xc20807af78 main.main() /home/csy/goitem/src/mendicant/test/testmain.go:20 +0x2f fp=0xc20807af98 sp=0xc20807af80 runtime.main() /usr/local/go/src/runtime/proc.go:63 +0xf3 fp=0xc20807afe0 sp=0xc20807af98 runtime.goexit() /usr/local/go/src/runtime/asm_amd64.s:2232 +0x1 fp=0xc20807afe8 sp=0xc20807afe0 goroutine 17 [syscall, locked to thread]: runtime.goexit() /usr/local/go/src/runtime/asm_amd64.s:2232 +0x1
