Hi,
custom compilation using php-fpm crashes sometimes, actual version is 7.2.6
[755816.604490] php-fpm[35668]: segfault at 7f45d742b760 ip 000000000082f4ff sp 00007fffc2c83700
error 4
.crash
ProcStatus
Name: php-fpm
State: S (sleeping)
Tgid: 35668
What does it mean it's in State: S (sleeping)?
gdb bt
Reading symbols from /var/www/sbin/php-fpm...done.
[New LWP 35668]
warning: .dynamic section for "/usr/lib/x86_64-linux-gnu/libxml2.so.2" is not at the
expected address (wrong library or version mismatch?)
warning: .dynamic section for "/lib/x86_64-linux-gnu/libcrypto.so.1.0.0" is not at the

warning: Could not load shared library symbols for 2 libraries, e.g.
/lib/x86_64-linux-gnu/libnss_winbind.so.2.
Use the "info sharedlibrary" command to see the complete listing.
Do you need "set solib-search-path" or "set sysroot"?

I know, this is not much info
Does it help to search for a bug, if I install a version with enable-debug?
thanks
