Previous Comments: ------------------------------------------------------------------------ [2004-07-13 22:41:13] chris at leftbrained dot org I'm still experiencing this issue, exactly as described, using a build from this mornings CVS. I'm using Apache2 and Windows 2k Pro, with PHP compiled as a module, and lib_mysql and lib_mysqli in use. I'm available for any tests that might be necessary, though I'm not comfortable compiling PHP on Windows. ------------------------------------------------------------------------ [2004-06-28 01:19:54] rashid at ds dot pg dot gda dot pl some more precise info in above example: $total = $temp = 0 i tried other settings: $total = $temp = '0' still caused error. $total = $temp = '0.0' worked fine hope this info helps - it looks like some kind of variable type conversion problems ------------------------------------------------------------------------ [2004-06-18 14:36:44] rashid at ds dot pg dot gda dot pl Description: ------------ description in http://bugs.php.net/bug.php?id=27759 describes the problem well. there is also the same problem with bcsub. its reported again because the bug is still present in latest cvs build. Reproduce code: --------------- PEAR`s Benchmark_Timer::getProfiling(): //... this is part of loop - first settings of parameters are empty, and apache throws exception right away $diff = bcsub($time, $temp, 6); $total = bcadd($total, $diff, 6); //... Actual result: -------------- apache exception ['memory cannot be read'] ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28829&edit=1
