Bug ID: 239520
Summary: Possible memory leak in newlocale/uselocale
Product: Base System
Version: 12.0-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: misc
Assignee: b...@freebsd.org
Reporter: a.shi...@itcons.net.ua
Hello!
Running the binary compiled from the simple code
#include <locale.h>
int main() {
while (1) {
locale_t n = newlocale(LC_TIME, "en_AU.UTF-8", (locale_t)0);
locale_t old = uselocale(n);
uselocale(old);
freelocale(n);
}
}
results to rapid memory leak. It was tested on 12.0-RELEASE/amd64,
11.2-RELEASE/amd64 and 9.3-RELEASE-p53/i386.
First time the problem with memory leak was found with Perl 5.28 and Perl 5.30
on 12.0-RELEASE/amd64. The firt suspicion was about Perl, but further
discussion came to this test C code. Discussion on rt.perl.org:
