Unknown sym formats on macOS / Go 1.13

[fgm]

On macOS Mojave, Go 1.13, when using tab2pydic, I get thousands of errors for unknown formats, like these, selecting only a few from each error type:

unknown B sym format: _runtime/cgo(__DATA/__bss)
unknown B sym format: golang.org/long long/net/html.ErrBufferExceeded
unknown D sym format: _runtime/cgo(__DATA/__data)
unknown D sym format: golang.org/long long/net/html..gobytes.1
unknown R sym format: _crypto/x509(__TEXT/__const)
unknown R sym format: _crypto/x509(__TEXT/__cstring)
unknown R sym format: _runtime/cgo(__TEXT/__const)
unknown R sym format: _runtime/cgo(__TEXT/__cstring)
unknown R sym format: go.func.*
unknown R sym format: go.itab.*bufio.Writer,golang.org/long long/net/html.writer
unknown T sym format: _crypto/x509(__TEXT/__text)
unknown T sym format: _runtime/cgo(__TEXT/__text)
unknown T sym format: golang.org/long long/net/html.(*Node).AppendChild
unknown format:            16781312 U _CFArrayGetCount
unknown format:            16781312 U _CFArrayGetValueAtIndex

The tool seems to work nonetheless, but I wonder whether the results are correct, given all these errors.

I am getting the same errors too on Go 1.13.5 on Windows

This is made to work on linux

we've improved this in the last version, feel free to try it out

Thanks. There is still a similar quantity of warnings, but one does get some results in the end. Without the names until one clicks on a square, and with a big "unknown" chunk, but at least some info appears

The warnings are mostly like this:

unknown B sym format: _runtime/cgo(__DATA/__bss)
unknown D sym format: _runtime/cgo(__DATA/__common)
unknown R sym format: _runtime/cgo(__TEXT/__const)
unknown R sym format: _type:*
unknown R sym format: crypto/ecdh..dict.nistCurve[*crypto/internal/nistec.P256Point] (tons of those)
unknown T sym format: _go:buildid
unknown T sym format: _runtime/cgo(__TEXT/__text)
unknown T sym format: crypto/ecdsa.hashToNat[go.shape.*uint8] (tons of those)
unknown format:          4294971392 U _CFArrayAppendValue (appears to be darwin-specific)
unknown format:          4294971392 U _ptrace (appears to be standard syscalls)

(FWIW: 4294971392 is actually 2^32 - 2^12)
