i586-mandrake-linux-gnu
>Description:
make test fails with a particular combination, and only that combination so far, of optimization flags.
CFLAGS="-O2 -frename-registers -fomit-frame-pointer -mcpu=pentiumpro -fPIC"
>How-To-Repeat:
I am sorry but I don't have a testcase at this point.
1) Get zlib-1.1.4 sources
2) Configure as follows: CFLAGS="-O2 -frename-registers -fomit-frame-pointer -mcpu=pentiumpro -fPIC" ./configure --shared
3) make; make test
>Fix:
Remove one (any of) the CFLAGS.
