Yeah, I guess attempt to commit a C file with 700K lines of code won’t end well for a developer. Thanks for clarifying things! > On 14 Mar 2016, at 17:05, C Bergström wrote: > > I don't speak with any community authority - I think your test tool is > misconfigured then. I don't see any pragmat

I don't speak with any community authority - I think your test tool is misconfigured then. I don't see any pragmatic reason to generate such a test. It's unlikely to mirror any real world code and artificial test cases like this, at best only serve as some arbitrary data point. On Mon, Mar 14, 201

Is test case with 700k lines of code a valid test case?

2016-03-14 Thread Andrey Tarasevich
Hi, I have a source file with 700k lines of code 99% of which are printf() statements. Compiling this test case crashes GCC 5.3.0 with segmentation fault. Can such test case be considered valid or source files of size 35 MB are too much for a C compiler and it should crash? It crashes on Ubuntu
