[Bug c++/35261] New: GCC4.3 internal compiler error: verify_flow_info failed

[rajiv dot adhikary at amd dot com]

Compiling using GCC4.3 with

            g++ -msse4.1 -O2 -c  repro.cpp

causes internal compiler error:

repro.cpp: In function 'int main()':
repro.cpp:122: error: BB 10 can not throw but has EH edges
repro.cpp:122: internal compiler error: verify_flow_info failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.



In this file the error goes away if you change

            const static repro_u32 LOOP_COUNT = 100 * 1000;

to

            const static repro_s32 LOOP_COUNT = 100 * 1000;

 Alternately if I remove the creation of Timer object (comment out Timer t(
pass, expCycles ); ) the problem goes away.

bug.ii

I ran into this same error with different code, which I posted to
<http://gcc.gnu.org/ml/gcc-help/2008-04/msg00190.html> but reduced further to
the attached. It, like the original code, fails with GCC 4.3.0, GCC
4.3-20080410, and GCC-4.4-20080411, when GCC is configured with
--enable-checking. gcc -c -O is enough to show it with this:

$ ~/gcc/bin/gcc -c -O bug.ii
bug.ii: In function ‘void h()’:
bug.ii:7: error: BB 13 can not throw but has EH edges
bug.ii:7: internal compiler error: verify_flow_info failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
$ ~/gcc/bin/gcc --version

------- Comment #3 from pinskia at gcc dot gnu dot org  2008-12-28 06:52 -------
Both of these work on the trunk on i386-darwin8.11, Do you know if it works on
the 4.3 branch?
