Reproducible: Always Steps to Reproduce: 1. set USE="mpm-peruser" 2. emerge =apache-2.2.6 3. Actual Results: *kaboom*
Created attachment 130537 [details, diff] Add #define AP_MPM_WANT_FATAL_SIGNAL_HANDLER to peruser/mpm.h Works for me
do not compile with USE=debug
erm, scratch the WONT, i have add it to the patch in svn, will be in the next revision
