Description Lukasz Kosewski 2005-03-24 02:55:43 UTC
I have a very simple program here, namely:
#include <malloc.h>

void __attribute__((malloc)) intersect(int list)
    int* shite = (int *)malloc(sizeof(int));

int main()

Attempting to compile this using GCC 3.4 with `gcc bug.c` causes a segmentation

Output of `gcc -v --save-temps bug.c`:

This interface for bug submissions is horrible (no offense).  If I can figure
out how to attach files to this bug, I will attach the .i file.

Created attachment 8442 [details]
The attached .i file and original source.

This contains the original source which produced the error, as well as the .i
file which I get out of it.
Comment 2 Andrew Pinski 2005-03-24 03:02:24 UTC
Yes but this is a dup of bug 15443.  A simple seach would have found it
