I'm running apache 2.4.49 on
* 10.6.8
* 10.15.7
without any issues
That brackets the problem a bit.
Given the odd failure ("crashed on child side of fork pre-exec" with a
segfault) I suspect it is something specific to the platform, e.g.
compiler version, shared library versions, etc. and I'm experimenting
with rebuilding it in different ways to see if I can find a way to
make it work.
Currently running with '-X' as a workaround (doesn't fork...)
Closing the loop here:
Rebuilding httpd and everything it recursively depends on with clang-10
on the target system didn't touch the problem. Reverting to .48 didn't
touch the problem(!) Limping along and waiting for the .51 update
resolved the problem. I did not test .50, which lasted just a few days.
I'm not up to analyzing all the flux in the httpd code between those
versions, but there are enough core and mpm fixes that I'm satisfied
with vague handwaving about something jostling an optimization in the
wrong/right place and for 2 minor versions breaking it on one obsolete
platform.

Apache httpd 2.4.49 port will not launch on ElCap
I've used the prebuilt binary and done a source build myself, it just won't launch. A few startup messages are in the ErrorLog, but they don't note any reason for the crash. The OS does manage to save crash reports when I try to start, all looking similar to the one below. Googling about various specifics from the crash report (e.g. https://stackoverflow.com/questions/55286016/python-is-crashing-due-to-libdispatch-crashing-child-thread) makes me suspect that this has something to do with how httpd initializes itself. Telling bit is the "crashed on child side of fork pre-exec" I'm wondering if anyone else has encountered this and if anyone has a sense of whether this is really a MacPorts-specific problem or if it is (as I suspect but have not been able to confirm) a problem with httpd.
