That may be. The "malloc" message in the httpd error_log is specific to this
crash in apr_allocator_destroy(). But, looking at the crash logs, I see also
crashes in apr_bucket_free(), apr_palloc() and apr_brigade_writev().

I can attach sample crash-reporter logs for those as well.

I don't know how to reproduce the crashes. They happen sporadically, maybe a
dozen or two times a day:

% grep 2006-03-13 /Library/Logs/CrashReporter/httpd.crash.log | wc -l
      20
% grep 2006-03-14 /Library/Logs/CrashReporter/httpd.crash.log | wc -l
      16
% grep 2006-03-15 /Library/Logs/CrashReporter/httpd.crash.log | wc -l
      20
% grep 2006-03-16 /Library/Logs/CrashReporter/httpd.crash.log | wc -l
      19
% grep 2006-03-17 /Library/Logs/CrashReporter/httpd.crash.log | wc -l
      17
% grep 2006-03-18 /Library/Logs/CrashReporter/httpd.crash.log | wc -l
      10
% grep 2006-03-19 /Library/Logs/CrashReporter/httpd.crash.log | wc -l
      12
% grep 2006-03-20 /Library/Logs/CrashReporter/httpd.crash.log |wc -l
      46

Looking at the access logs, I don't see any sort of pattern in the requests
immediately preceding a crash.

Of course, since there are several child processes servicing requests, I'm
mostly staring at entries produced by children that *didn't* crash. Buried among
them is the child process that did.

I can probably rule out SSL requests, as there are very few of those/day and
probably none coinciding with the crashes. Maybe mod_deflate or mod_include ... 
?
