Hello!

a SSI bug in 0.7.19 but not in 0.6.32 results in "worker process NNNNN exited on signal 10 (core dumped)" if I have many include instructions in one file. 5 includes are ok, 6 not. See details below.

Could you please check if the following patch fixes this?

diff --git a/src/core/ngx_palloc.c b/src/core/ngx_palloc.c --- a/src/core/ngx_palloc.c +++ b/src/core/ngx_palloc.c @@ -171,6 +171,7 @@ ngx_palloc_block(ngx_pool_t *pool, size_ new->d.next = NULL;

m += sizeof(ngx_pool_data_t); + m = ngx_align_ptr(m, NGX_ALIGNMENT); new->d.last = m + size;

current = pool->current;
