MySQL crash problems

A bunch of people have been reporting problems with Apache crashing on startup when MySQL support is compiled in. I have compiled the latest Apache-1.3.12-dev/MySQL-3.23.11/PHP3.0.15-dev code a bunch of times over the past couple of days. I finally managed to recreate the problem when I was helping someone else compile all this stuff. Basically what it boils down to is that when I use the latest 3.23 rpms I get problems, but if I compile from the tarball I am fine. From looking at the .spec file it looks like the shared library version of the mysql client libs are built thread-safe whereas the static client libs are built non-threadsafe. Is there a reason for this? The relevant part of the .spec file is: BuildMySQL "--enable-shared --enable-thread-safe-client --without-server" # Save everything for debus tar cf $RBR/all.tar . # Save shared libraries (cd libmysql/.libs; tar cf $RBR/shared-libs.tar *.so*) # Save manual to avoid rebuilding mv Docs/manual.ps Docs/manual.ps.save make distclean mv Docs/manual.ps.save Docs/manual.ps BuildMySQL "--disable-shared" \ "--with-mysqld-ldflags='-all-static'" \ "--with-client-ldflags='-all-static'" If I just grab the tarball instead of using the rpms and compile it without any special configure flags Apache/PHP/MySQL works fine. This is a nasty one because there is absolutely no error message in any log. A gdb trace shows a memory access error on the dlopen() of the PHP DSO in Apache. -Rasmus
