With gcc 7.5.0, I run into: ... (gdb) print objects^M $1 = ((tag => object, values => ()), (tag => unused))^M (gdb) FAIL: gdb.ada/array_of_variant.exp: scenario=minimal: print entire array ... while with gcc 8.5.0 we have: ... (gdb) print objects^M $1 = ((tag => object, values => (2, 2, 2, 2, 2)), (tag => unused))^M (gdb) PASS: gdb.ada/array_of_variant.exp: scenario=minimal: print entire array ... This is due to a gcc PR, which I've filed at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101633 "Bug 101633 - [debug] DW_TAG_subrange_type missing DW_AT_upper_bound". Fix by marking this and related FAILs as XFAIL. Tested on x86_64-linux. gdb/ChangeLog: 2021-07-27 Tom de Vries <tdevries@suse.de> PR testsuite/26903 * gdb/testsuite/gdb.ada/array_of_variant.exp: Add xfails.
