[Bug c++/112680] New: g++-13 segfault on std::regex_match with c++11 or above -O2 and lto
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112680
Bug ID: 112680
Summary: g++-13 segfault on std::regex_match with c++11 or
above -O2 and lto
Product: gcc
Version: 13.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: costamagnagianfranco at yahoo dot it
Target Milestone: ---
Created attachment 56672
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=56672=edit
reproduce test case
This used to work with g++-10 and started to fail with g++-11 g++-12 and g++-13
sh runme.sh
Segmentation fault (core dumped)
g++-12 main.cpp -std=c++11 -O2 -flto=auto -o main && ./main
The main is really simple, load two strings, and call regex function
#include
#include
#include
#include
int main()
{
std::ifstream t("file.txt");
std::stringstream file;
file << t.rdbuf();
std::string filestr = file.str();
std::ifstream t2("regex.txt");
std::stringstream filepathregex;
filepathregex << t2.rdbuf();
std::string regexstr = filepathregex.str();
const std::regex regex(regexstr);
std::regex_match(filestr.begin(), filestr.end(), regex);
}
I attached the tarball with the files to reproduce the issue.
The content triggering the issue was originated by the testsuite dump of

reduced testcase:
typedef struct {

typedef dt_aligned_pixel_t[4];
#pragma omp declare simd
void dt_bilateral_splat(dt_bilateral_t *b) {
int oy = b;

for (int i; i < b->width; i++) {

buf[offsets[k]] += contrib[k];
}
float *dest, *src = oy;
for (int i = 0; i < oy; i++)
dest[i] += src[i];
}
}
removing openmp, fstack-protector-strong or ffast-math works.
