Message: Logged In: YES user_id=2217 Hm, not really... The test case above still fails with both 1.30.5 and 1.40.0-alpha.

This makes makecstring() memory grow on demand. Also increase MAX_CSTRING_LEN in ptexmac.h to e. g. 10000000. ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=444&group_id=106
