I've reduced it. It's code like below where a memcpy confused
StackSafetyAnalysis in a macOS+libc++ build.
```cpp
int floatsuffix_check(TParseContext *context)
{
struct yyguts_t *yyg = (struct yyguts_t *)context->getScanner();
if (context->getShaderVersion() < 300)
{
context->error(*yyg->yylloc_r, "Floating-point suffix unsupported prior
to GLSL ES 3.00", yyg->yytext_r);
return 0;
}
std::string text = yyg->yytext_r;
text.resize(text.size() - 1); /////////
if (!strtof_clamp(text, &(yyg->yylval_r->lex.f)))
yyg->yyextra_r->warning(*yyg->yylloc_r, "Float overflow",
yyg->yytext_r);
return (FLOATCONSTANT);
}
```
