Especially if you turned on the dwarf2 unwinder, they > shouldn't be there. Hmm, I'm getting a bunch of "Unhandled dwarf expression opcode" messages. The opcode in question is 0x93, DW_OP_piece. I tweaked the error message in dwarf2expr.c::execute_stack_op() to print the opcode as well, so what I get is e.g. this: [...] continue^M Continuing.^M wack_longest (u=Unhandled dwarf expression opcode: 0x93^M ) at /home/corinna/src/gdb/src/gdb/testsuite/gdb.base/store.c:101^M 101 register longest l = u, r = v;^M (gdb) PASS: gdb.base/store.exp: continue to wack_longest next^M 102 l = add_longest (l, r);^M (gdb) PASS: gdb.base/store.exp: next longest print l^M $17 = -1^M (gdb) PASS: gdb.base/store.exp: print old l - longest print r^M Unhandled dwarf expression opcode: 0x93^M (gdb) FAIL: gdb.base/store.exp: print old r - longest What does that mean? How does that affect the approval of my code as it is now? Corinna -- Corinna Vinschen Cygwin Developer Red Hat, Inc.
