           Summary: apr_palloc Segmentation Fault
           Product: APR
           Version: 1.4.2
          Platform: PC
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: APR
        AssignedTo: bugs@apr.apache.org
        ReportedBy: marcelo@tpn.com.br


I'm using an experimental mpm called peruser (http://www.peruser.org/).

My server is segfaulting, but I believe that there is some problem with
apr_palloc, because the last 5 frames in backtrace are from original Apache
source.

I'm using Apache 2.2.16 version, but this problem also happened with Apache
2.2.17 and APR 1.4.2.

Here is the backtrace:
