Hi,
   I am working on a small implementation in gcc-code. I declare some
data structures, using GTY(()) tag ..and allocate elements using ggc_alloc_cleared function.
To free data, i use ggc_free function.
The problem is that many a times i get strange memory allocation segfaults in xcalloc/xmalloc. In case i don't free any allocated memory, things work fine most of the times. What could be the problem above. Also what is the correct method of allocating and dealloction of data/arrays in gcc ? Please help as i am already bugged by these errors :(, and this is urgent for my project.

Thanks and Regards,
Virender
