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

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.
