I'm seeing this one fail is some configurations, but only in the
'build-gcc/libbacktrace/btest_lto.log' variant:
test5: unexpected syminfo name got global.2537 expected global
PASS: backtrace_full noinline
PASS: backtrace_full inline
PASS: backtrace_simple noinline
PASS: backtrace_simple inline
FAIL: backtrace_syminfo variable
FAIL btest_lto (exit status: 1)
I haven't looked yet which details about these GCC build configurations
might be different/important; maybe you've got an idea already?
Grüße
Thomas
