Description of problem: When malloc debugging is enabled, which the latest initscripts-8.79-1.fc10 does system-wide, glibc prints a message to stderr (or is it stdout?) for every single program starting up: malloc: using debugging hooks That breaks programs like uname, at least cmake gets confused by the uname output and prints: System is unknown to cmake, create: Platform/malloc: using debugging hooks Linux to use this system, please send your config file to cmake.org so it can be added to cmake and errors, breaking KDE package builds. If debugging is to be enabled system-wide in Rawhide, it has to be silent unless/until an error occurs. Version-Release number of selected component (if applicable): glibc-2.8.90-8 initscripts-8.79-1.fc10 How reproducible: Always Steps to Reproduce: 1. Try running a build with the latest glibc and initscripts. Actual results: build.log gets spammed with "malloc: using debugging hooks", cmake gets confused and errors. Expected results: Use of debugging hooks is silent. Additional info: See also http://fedorahosted.org/rel-eng/ticket/733
Changed in 2.8.90-9.
The same problem is in RHEL-5
Debugging hooks is ON. check: echo $MALLOC_CHECK_ It is probably in 1. To solve your problem, enter: export MALLOC_CHECK_=0
