Add constructor to stap_static_probe_ops
PR build/24937 concerns an error given by the clang provided by a particular version of macOS. In particular, it reports error: default initialization of an object of const type 'const stap_static_probe_ops' without a user-provided default constructor Although (at least according to sources I found online) this was resolved as a bug in the standard, it seemed simple enough to work around this. Given that this is a trivial build fix, I think it should go on the gdb 9 branch as well. gdb/ChangeLog 2020-01-07 Tom Tromey <tromey@adacore.com> PR build/24937: * stap-probe.c (class stap_static_probe_ops): Add constructor.
