Hi Jerry,

Hi Wolfgang,

I'm the Fedora maintainer, so those patches are my fault. :-)  One of
them makes it unnecessary to switch off brk randomization for the
entire box, if that matters to you (gcl-2.6.8-unrandomize.patch).

I tried two patches from a gcl-2.6.7-14.fc7 source RPM I happened two find somewhere on the web. The first one, gcl-bash.patch, solved a syntax error in the configure script, the other one, gcl-pers.patch, seems to be supposed to work around the brk randomization problem, but this did not work for me, I still had to disable the randomization. Probably there are newer and better patches, I just used, what I found by googling. Anyway, I'll give up with 2.6.7 and hope to get the CVS version to work.

Also, note that the -lz problem has been fixed in CVS, and a number of
the Fedora patches have been applied as well.

Yes, in the CVS the -lz problem and also the brk problem seem to be fixed.

Therefore I decided to use the CVS. This worked much better, but finally
also failed.

That's a strange failure.  I'm going to take a wild shot in the dark
here.  Does adding -fno-strict-aliasing to CFLAGS help?
I'll try this tomorrow, because I am not in my office yet. Many thanks for the tip.

best regards
