I have adopted the test case for s390 and it now stops at main, which is identical to x86. The --symfs option was not used, however the debug file selected for dwarf examination was different. With you patch it changed from /usr/lib64/libc.so (old) to /usr/lib/debug/lib64/libc-2.26.so.debug (new) and I think that this file has not all the info (at least on s390). -- Thomas Richter, Dept 3303, IBM s390 Linux Development, Boeblingen, Germany -- Vorsitzende des Aufsichtsrats: Martina Koederitz Geschäftsführung: Dirk Wittkopp Sitz der Gesellschaft: Böblingen / Registergericht: Amtsgericht Stuttgart, HRB 243294
