Subject: Ensure Ident_GNU_final is properly initialized in the Parser Initialize function
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c892f14b89623d6e479f8d69f30ae34a4e631417;p=clang

Ensure Ident_GNU_final is properly initialized in the Parser Initialize function

The recent change implementing __final forgot to initialize a variable.
This was caught by the Memory Sanitizer.

Properly initialize the value to nullptr to ensure proper memory reads.

Patch by Erich Keane!
