--- Comment #7 from Rainer Orth <ro at gcc dot gnu.org> --- Created attachment 58276 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=58276&action=edit Minimal patch Minimal patch as described: just build src/libbacktrace with -funwind-tables, same for 19_diagnostics/stacktrace tests. Ran just the stacktrace tests on i386-pc-solaris2.11 and sparc-sun-solaris2.11 (32 and 64-bit each), all PASS now.
