A happy new year to the CRUX team and the 2.4 release! :-) I am about to plan a live-upgrade of a production machine from 2.3 to 2.4. During some test-builds, I ran into a little problem while building the current m4-1.4.10 on an i686 environment: conftest segfaults during the ./configure process of m4 while checking whether printf supports infinite 'long double' arguments... no It can be noticed in the kernel log (if appropriate logging is enabled): Jan 4 14:00:53 box74238 kernel: conftest[30531]: segfault at 0804b000 eip b7e7796c esp bfae34a0 error 6 This was also reported on an x86_64 system: http://www.nabble.com/m4-1.4.10-segfault-with-x86_64-during-.-configure-when-checking-whether-printf-supports-infinite-'long-double'-arguments-td14320530.html Does anybody run into similar things? Can you please check by a simple pkgmk m4? I am not sure about which fix is the correct approach. Several patches are mentioned in above thread. Any ideas here?
