It occurs on recent 7.4 beta, but also in current 7.2 and probably dates back much further. The crash is due to the following snippet in file ext/iconv/config.m4: int main() { iconv_t cd = iconv_open( "UTF-8//IGNORE", "UTF-8" ); => no check for result of iconv_open here! char *in_p = "\xC3\xC3\xC3\xB8"; size_t in_left = 4, out_left = 4096; char *out = malloc(out_left); char *out_p = out; size_t result = iconv(cd, (char **) &in_p, &in_left, (char **) &out_p, &out_left); if(result == (size_t)-1) { return 1; } return 0; } Test script: --------------- Run configure on Solaris 10 Sparc. config.log shows: configure:37401: checking if iconv supports //IGNORE ... configure:37435: ./conftest ./configure[20]: 4274 Bus Error(coredump) configure:37435: $? = 138 configure: program exited with status 138 -- Edit bug report at https://bugs.php.net/bug.php?id=78342&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=78342&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=78342&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=78342&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=78342&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78342&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78342&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78342&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78342&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78342&r=support Expected behavior: https://bugs.php.net/fix.php?id=78342&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78342&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78342&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78342&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=78342&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=78342&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78342&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78342&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78342&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78342&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78342&r=mysqlcfg
