Bug ID: 119183
Summary: Compilation Timeout Issue
Product: gcc
Version: 14.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: xieym3 at zohomail dot com
Target Milestone: ---
The following code snippet fails to complete compilation within a reasonable
timeframe using GCC versions 11.4.0, 14.2.0, and current trunk.
$ timeout 300 gcc -x c -std=c2x file.c
$ cat file.c

int test()
{
int a = rand();
if(a >= 0 )
return a*a + rand() + rand();
else
return rand() - 1;
}
void main(int argc, char** argv){
float sum = 0.0;
