New ICE in 3.1 branch: remove_eh_handler, at except.c:2696

New ICE in 3.1 branch: remove_eh_handler, at except.c:2696

[Roberto Bagnara]

Dear all,

I am monitoring the 3.1 branch and making frequent cvs updates and
rebuilds so as to make sure that the to-be-released 3.1 and my software
go well together.  A few days ago the following started happening:

$ /opt/bin/g++ -c ppl_c.ii
/home/roberto/ppl/ppl/interfaces/C/ppl_c.cc: In function `int
    ppl_Coefficient_OK(const ppl_Coefficient_tag*)':
/home/roberto/ppl/ppl/interfaces/C/ppl_c.cc:196: Internal compiler error in
    remove_eh_handler, at except.c:2696
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

Last time I tried was 8 hours ago with

$ /opt/bin/g++ -v
Reading specs from /opt/lib/gcc-lib/i686-pc-linux-gnu/3.1/specs
Configured with: ../gcc/configure --prefix=/opt : (reconfigured) ../gcc/configure --prefix=/opt
Thread model: single
gcc version 3.1 20020411 (prerelease)

The same code compiles OK with GCC 3.0.4.
The testcase ppl_c.ii will be available for some time at

     ftp://ftp.cs.unipr.it/pub/ppl_c.ii.bz2

I hope this helps.
All the best

      Roberto
