A few days ago I noticed a little problem when compiling programs
that use gets() and other functions that cause those warnings we all
know and love...
Try the following:
1) # ln -sf AJ /etc/malloc.conf
2) # cc -o test test.c
---------------------------------
test.c:
---------------------------------
#include <stdio.h>
int main()
{
char *s;
gets(s);
}
--------------------------------
Yeah, it's stupid, but it shouldn't cause this:
# cc -o test test.c
/var/tmp/ccBY97461.o: In function `main':
/var/tmp/ccBY97461.o(.text+0xb): cc: Internal compiler error: program ld got fatal signal 11
Or alternatively:
# cc -o test -lc_r test.c
/var/tmp/ccDI97511.o: In function `main':
