Hi all,
P.S. The bug proves that no one ever ran `make check' on PPL 0.10 on a PowerPC machine and reported back the results. If you have any idea how to make sure this does not happen again...
Finally ppl 0.10-2 has made its way through nearly all the build daemons (armel is missing, but arm was ok), and only a single check fails, and it only fails on alpha: generalizedaffineimage2 (from Octagonal_Shape) results in an uncaught exception. See also http://buildd.debian.org/build.php?&pkg=ppl&ver=0.10-2&arch=alph...
Do you have access to an alpha machine or can you tell from the source what could be going wrong there? Of course, it may also be an architecture-specific compiler problem ...
If you need any help, just contact me.
We've tried hard, but we've been unable to reproduce this behavior using stock PPL 0.10 configured as found in your log file:
configure --build alpha-linux-gnu --host alpha-linux-gnu --enable-interfaces=c,cxx --disable-ppl_lpsol --disable-ppl_lcdd CFLAGS="-Wall -g -O2"
It would be very interesting to check with gdb where the untrapped exception has been generated.
Here below you find info about testing machine (which is the only alpha we have access to).

Hi Michael,
would it be possible to access a machine where the problem manifests itself? Alternatively, can someone run that test program under GDB and tell us which exception is thrown? All the best,
Roberto
