Hi Dehao, I suspect that your recent patch changing block handling has
broken bootstrap with --enable-languages=go. I reduced the test case
to this C++ code:
#include string
std::string
f(bool is_string, bool is_constant)
{
if (is_string)
{
std::string left_string;
std::string
Sure, I'll look into this problem today.
Thanks,
Dehao

The bug is in tree-eh.c. IS_UNKNOWN_LOCATION is mistakenly used, thus
the block info for a call stmt is cleared.
A patch to fix the problem is atached:
gcc/ChangeLog:
tree-eh.c (lower_try_finally_dup_block): Use correct way to
check unknown location.

While you think about my questions, let's fix the bootstrap. This
patch is OK if it passes bootstrap and a gcc and
IS_UNKNOWN_LOCATION checks if the source location is unknown.
== UNKNONW_LOCATION checks if source location is unknown and the block is NULL.
Yes, they are error-prone, I'll have a separate patch to clean up
IS_UNKNOWN_LOCATION later.

Hi, Ian,
This patch fixed the bootstrap problem, as well as the problem posted
in http://gcc.gnu.org/ml/gcc-patches/2012-09/msg01441.html
However, the libstdc++ problem is not fixed, they are related to the
my line_table implementation for PCH. I'll send another patch later
for that.
Shall I
