[Bug other/37463] New: [4.4 regression] All Solaris/x86 eh tests fail

["ro at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Now that i386-pc-solaris2.10 bootstraps again after the IRA merge, the first
testsuite run revealed that all eh tests fail, affecting at least the g++
tests,
ada/acats and libjava.  The symptom is always the same; I take

FAIL: g++.dg/eh/alias1.C execution test

as an example.

Running alias1.exe under gdb, I get the following stacktrace:

Program received signal SIGABRT, Aborted.
0xfedf5cd5 in _lwp_kill () from /lib/libc.so.1
(gdb) up
#1  0xfedf2b96 in thr_kill () from /lib/libc.so.1

#7  0x08050b51 in main ()

So the gcc_assert call in _Unwind_SetSpColumn causes this.

Maybe one of the recent dwarf2 undwind patches has caused this?

gcc was configured with --with-gnu-as --with-as=/usr/sfw/bin/gas, where
/usr/sfw/bin/gas is gas 2.15.  gcc/auto-host.h has

auto-host.h:#define HAVE_GAS_CFI_DIRECTIVE 1
auto-host.h:#define HAVE_GAS_CFI_PERSONALITY_DIRECTIVE 0

I'm filing this under other since no other component seemed appropriate.
