Comment(by cypherpunks):

 {{{
 tor_assert(len < INT_MAX && len < SIZE_T_CEILING);
 }}}
 len is ssize_t (signed).
 Hopes no one platform defines those constants as unsigned.
 Except it does Tor, for missed defines:
 {{{
 #ifndef INT32_MAX
 #define INT32_MAX 0x7fffffffu
 }}}
 {{{
 #ifndef SSIZE_T_MAX
 #if (SIZEOF_SIZE_T == 4)
 #define SSIZE_T_MAX INT32_MAX
 }}}

 Fix:
 {{{
 tor_assert(len < (ssize_t)INT_MAX && len < (ssize_t)SIZE_T_CEILING);
 }}}
