Still investigating. ------------------------------------------------------------------------ [2004-06-10 15:38:24] steveh at brendata dot co dot uk Ok, it's related to the size of the column name, probably a buffer overflow, reducing the length of a generic prefix has removed the problem for now. ------------------------------------------------------------------------ [2004-06-10 15:29:42] steveh at brendata dot co dot uk Description: ------------ I'm still working out the circumstances and removing code to prove what is causing the issue, but at present, both the apache module and the cli php are core dumping with the following backtrace. Reproduce code: --------------- This will follow when I find out what's causing the issue. Expected result: ---------------- No core dump?
