thanks for your comments. Taking in count tha changes provided i still face
this problem:

#0  0x00000000004065d6 in ngx_palloc (pool=0x0, size=16) at
src/core/ngx_palloc.c:122
#1  0x0000000000406a73 in ngx_pcalloc (pool=0x0, size=16) at
src/core/ngx_palloc.c:305
#2  0x000000000046b76d in ngx_http_chunked_header_filter (r=0x6eebb0)
    at src/http/modules/ngx_http_chunked_filter_module.c:82
#3  0x000000000046bdc4 in ngx_http_range_header_filter (r=0x6eebb0)
    at src/http/modules/ngx_http_range_filter_module.c:160
