0842175 (not in any release) used the wrong format specifier (long int) for timediff_t. On an OS such as Windows libcurl's timediff_t (usually 64-bit) is bigger than long int (32-bit). In 32-bit Windows builds the upper 32-bits of the timediff_t were erroneously then used by the next format specifier. Usually since the timeout isn't larger than 32-bits this would result in null as a pointer to the string with the reason for the connection failing. On other OSes or maybe other compilers it could probably result in garbage values (ie crash on deref).
