These new tests are all failing on my i686-pc-linux-gnu system.
sigaltstack.exp fails like this:
finish
Run till exit from #0 catcher (signal=26) at /opt/src/gdb/src/gdb/testsuite/gdb.base/sigaltstack.c:71
Warning:
Cannot insert breakpoint 0.
Error accessing memory address 0xffffe420: Input/output error.
(gdb) FAIL: gdb.base/sigaltstack.exp: finish from catch LEAF
The problem is that the signal trampoline is read-only. We can't set
software breakpoints there. I suspect there is no way to do this portably.
Should we skip it instead, i.e. finish right to the place where the signal
was raised?
