Bug #75696 [NEW]: posix_getgrnam fails to print details of group

From: jas at eecs dot yorku dot ca Operating system: CentOS 7.4 PHP version: 7.2.0 Package: POSIX related Bug Type: Bug Bug description:posix_getgrnam fails to print details of group Description: ------------ I think I've discovered an odd bug. When I use "posix_getgrnam" to print details on a group in /etc/group, I get back nothing. If I erase one entry from the group above it, then it works! example silly /etc/group file: root:x:0: labtest:*:31003:a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,aa,bb,cc,dd,ee,ff,gg,hh,ii,jj,kk,ll,mm,nn,oo,pp,qq,rr,ss,tt,uu,vv,ww,xx,yy,zz,aaa,bbb,ccc,ddd,eee,fff,ggg,hhh,iii,jjj,kkk,lll,mmm,nnn,ooo,ppp,qqq,rrr,sss,ttt,uuu,vvv,www,xxx,yyy,zzz,aaaa,bbbb,cccc,dddd,eeee,ffff,gggg,hhhh,iiii,jjjj,kkkk tech:*:1000:tdb Without removing user "kkkk" from "labtest" group, posix_getgrnam can't return the details for group tech! Test script: --------------- <?php print_r(posix_getgrnam("tech")); ?> Expected result: ---------------- I expect to see the group details for group "tech". Actual result: -------------- empty. -- Edit bug report at https://bugs.php.net/bug.php?id=75696&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75696&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75696&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75696&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75696&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75696&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75696&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75696&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75696&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75696&r=support Expected behavior: https://bugs.php.net/fix.php?id=75696&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75696&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75696&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75696&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75696&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75696&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75696&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75696&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75696&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75696&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75696&r=mysqlcfg
