runtime: TestGdbPython fails on OS X

[josharian]

The support script is not being loaded.

$ go test -run=Gdb -v runtime
=== RUN TestGdbPython
--- FAIL: TestGdbPython (0.29s)

This is not #8973 or #5221; the symbol is present.

This is not #9820; otool -s __DWARF __debug_gdb_scri a.exe yields the correct language identifier and script path.

Suggestions for what to try next? Objections to simply disabling the test on OS X, as most OS X users use lldb anyway?

it's a known bug of gdb on os x. i think it looks for __debug_gdb_script section although that section name is impossible for Mach-O.

Thanks, Minux. I was somehow convinced that it worked in Go 1.3...and I was wrong.
