4.11.3 Solaris x86

If you are using gcc or egcs on Solaris x86 and you experience problems with core dumps under load, you should use the following configure command:

shell> CC=gcc CFLAGS="-O6 -fomit-frame-pointer" \
       CXX=gcc \
       CXXFLAGS="-O6 -fomit-frame-pointer -felide-constructors -fno-exceptions -fno-rtti" \
       ./configure --prefix=/usr/local/mysql

This will avoid problems with the libstdc++ library and with C++ exceptions.

If this doesn't help, you should compile a debug version and run it with a trace file or under gdb. G.1 Debugguer un serveur MySQL.
