[Bug c++/27098] New: throw cause terminate() instead of catch

[mlazar at kma dot zcu dot cz]

I have two files. One in c compiled with gcc, and other in c++ compiled with
g++. From c++ is called helper function in c with pointer to error handler as
parameter. Error handler (in c++) execute throw, but it is not catched as I
expected. Instead is called default terminate() function.

I observe this bug on i685 in gcc-2.95 (debian), gcc-3.3.6 (debian), gcc-3.4.5
(gentoo), gcc-3.4.6 (ubuntu) and gcc-4.0.3 (ubuntu).

I also tested it on x86_64 in gcc-3.3.3 (SuSE). With -m32 i get this error but
with -m64 the exception is catched!

I observed that if the c source is compiled with "-foptimize-sibling-calls -O"
options (on i686 in gcc 4.0.3), the exception is catched.

So in this case, the terminate() function call:
gcc -c helper.c
g++ helper.o main.cc -o main

and this case, the exception is catched:
gcc -c helper.c -O -foptimize-sibling-calls
g++ helper.o main.cc -o main
