>Description:
gdb seems to not work at all with running processes on sparc64:
[/usr/tests/lib/libm] martin@thirdstage > gdb ./t_fe_round GNU gdb (GDB) 13.2
[..]
For help, type "help".
Type "apropos word" to search for commands related to "word"...
Reading symbols from ./t_fe_round...
(No debugging symbols found in ./t_fe_round)
(gdb) break nearbyint
Breakpoint 1 at 0x103100
(gdb) run -l
Starting program: /usr/tests/lib/libm/t_fe_round -l
thread.c:1337: internal-error: switch_to_thread: Assertion `thr != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
