Re: Bugs introduced in GCC?
In terms of actual volume of patches against upstream, and excluding SVN updates, the diff from the base Debian 4.2.3-2 version and Ubuntu 8.04's 4.2.3-2ubuntu7 is about 40 KB. > If so, what is it meant to change? Matthias (CCed) should be able to give more information on any particular patches that are of concern. I didn't even imagine trying to read them myself! It's just that the added bug (which I forwarded) made me worry. I'm glad you are working on fixing this, and I hope you will make a new release. -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
Bugs introduced in GCC?
Are the statements below true?
Is the Ubuntu patch really 5 MB?
If so, what is it meant to change?
From: John Regehr <[EMAIL PROTECTED]>
...the default C
compiler for Ubuntu [GNU/]Linux 8.04 is a patched gcc-4.2.3 which (on x86)
miscompiles this rather simple function:
int func_1 (void)
{
signed char l_11 = 1;
unsigned char l_12 = -1;
return (l_11 > l_12);
}
The emitted code returns 1 instead of 0. An unpatched gcc-4.2.3 compiles
this correctly. The patch for the Ubuntu version of this compiler is
larger than 5 MB.
