>Description:
When the inferior is sitting on a just hit breakpoint, and there's a signal pending (pass, nostop), a step / next will result in that breakpoint being re-hit. Ex:
(gdb) PASS: gdb.base/sigstep.exp: step on breakpoint, skip handler; resync
break 65
Breakpoint 13 at 0x1800c90: file /home/scratch/PENDING/2004-08-10-sigskip/src/gdb/testsuite/gdb.base/sigstep.c, line 65.
(gdb) PASS: gdb.base/sigstep.exp: step on breakpoint, skip handler; break infinite loop
continue
Continuing.
Breakpoint 13, main () at /home/scratch/PENDING/2004-08-10-sigskip/src/gdb/testsuite/gdb.base/sigstep.c:65
65 while (!done);
1: x/i $pc 0x1800c90 <main+168>: lis r9,385
(gdb) PASS: gdb.base/sigstep.exp: step on breakpoint, skip handler; continue to infinite loop
step
...
Breakpoint 13, main () at /home/scratch/PENDING/2004-08-10-sigskip/src/gdb/testsuite/gdb.base/sigstep.c:65
65 while (!done);
1: x/i $pc 0x1800c90 <main+168>: lis r9,385
(gdb) FAIL: gdb.base/sigstep.exp: step on breakpoint, skip handler; performing step
instead of re-hitting breakpoint 13, it should have advanced to the next line (66).
