* [Bug regex/1217] New: regcomp.c elicits uninitialized-variable warnings with GCC 4 @ 2005-08-20 0:05 eggert at gnu dot org 2005-08-20 0:06 ` [Bug regex/1217] " eggert at gnu dot org ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: eggert at gnu dot org @ 2005-08-20 0:05 UTC (permalink / raw) To: glibc-bugs-regex regcomp.c contains code that elicits uninitialized-variable warnings with GCC 4. The problem is that GCC isn't smart enough to see that when duplicate_node returns REG_ESPACE, the uninitialized storage is not used. I'll attach a straightforward patch that changes the signature of duplicate_node to avoid the warnings. My impression is that the patch also causes GCC to generate better code, but I haven't measured this. -- Summary: regcomp.c elicits uninitialized-variable warnings with GCC 4 Product: glibc Version: 2.3.5 Status: NEW Severity: minor Priority: P2 Component: regex AssignedTo: gotom at debian dot or dot jp ReportedBy: eggert at gnu dot org CC: glibc-bugs-regex at sources dot redhat dot com,glibc- bugs at sources dot redhat dot com http://sources.redhat.com/bugzilla/show_bug.cgi?id=1217 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 4+ messages in thread
