Subject: RE: [4.1 Regression] internal compiler error: verify_stmts failed.
I checked the gcc_4_0_0_release out from the cvs repository today and I have
tried it.
here the g++ version information
g++ -v
Using built-in specs.
Target: i686-pc-cygwin
Configured with:
/usr/cvs-src/gcc4/configure --verbose --enable-languages=c,c++ --enable-nls
--without-included-gettext --with-system-zlib --enable-interpreter --enable-
threads=posix --enable-sjlj-exceptions --disable-version-specific-runtime-li
bs --disable-win32-registry
Thread model: posix
gcc version 4.0.0
I have got the same error.
if the reduced testcase you extract from the http.ii compiled without
optimisation ( -O2), it seems okay
but if the optimisation option is applied, it fails
$ g++ -c -O2 -Wall -Wno-ctor-dtor-privacy reduced.cpp
reduced.cpp: In function 'wxString GetHeader()':
reduced.cpp:11: internal compiler error: in valid_in_set, at
tree-ssa-pre.c:1082
Please submit a full bug report,
with preprocessed source if appropriate.
See URL:http://gcc.gnu.org/bugs.html for instructions.
do you think this is the same problem? or a new one should be submitted.

Do you know if this also works with the 4.0 branch?
Reduced testcase:
class wxString;
extern __attribute__((dllimport)) char* wxEmptyString;
struct wxString {};
inline wxString wxGetEmptyString()
{
return *(wxString *)wxEmptyString;
}
wxString GetHeader()
{
return wxGetEmptyString();
}
This is very target dependent as the __attribute__ is which is causing the
problem.
