crash with recent crypto++ versions
« on: October 11, 2010, 01:18:09 AM »

It's into a gentoo ~amd64 system. With recent libcrypto++ versions amule crash at startup.

This is with net-p2p/amule-10305  USE="daemon debug geoip gtk nls remote stats unicode upnp (-aqua) (-kdeenablefinal) -plasma -xchat" .

The last portage version of crypto++ that work with amule is dev-libs/crypto++-5.5.2-r1  USE="sse3".

It was already the case with older versions of amule, but I didn't get the time to make some backtrace until now.

With dev-libs/crypto++-5.6.1 (the devs removed the USE flag), I get the following:

Wrong forum. Complain with the CryptoPP guys.
Or build CryptoPP without Assembler code (see its config.h).

Those guys are silly, I don't have the knowledge to build a test program for this bug, and they want it for a bug report!
Or build CryptoPP without Assembler code (see its config.h).
Thanks, it work.
