Using PHP/4.3.11RC2-dev (btw, is it intentional that pear installs to c:\php\pear\pear?) Same result - frequent access violation. stack trace: ntdll!RtlpCoalesceFreeBlocks+0x21 ntdll!RtlFreeHeap+0x2e9 msvcrt!free+0xc3 msvcrt!__crtsetenv+0x193 msvcrt!_putenv_lk+0x42 msvcrt!_putenv+0x20 WARNING: Stack unwind information not available.

(NB still using php 4.3.10) ------------------------------------------------------------------------ [2005-03-29 02:05:42] rob at wildlime dot com Installed php 4.3.11 RC1 (windows) to c:\php, but PEAR wont't install. The error on running go-pear.bat, accepting the defaults, is: "failed to write c:\php\pear\data\PEAR\.tmppackage.dtd" There is plenty of disk space and I'm using an admin account. ------------------------------------------------------------------------ [2005-03-23 04:07:10] rob at wildlime dot com Description: ------------ Experiencing an intermittent (once every 5-10 requests) access violation. btw, I have posted this to the PHP bug list rather than the PEAR one as it is a crash, not just a script error. Here's the info I can glean from the debugger. I'm afraid I don't have the debug builds.
