Some users have reported problems with SIGSEGV during connection disconnects. The latest patch fixes this problem by modifying code in file src/gssybapi.c in function GsDisconnect(), by moving the call to:
GciPerform(GsKeepArray, "remove:", &(conn->object), 1);
to before the free(conn); statement.
Courtesy of the fine folks at Computas, there is a version of GemConnect for Sybase version 1.1.1 modified to coexist with GemConnect for Oracle 2.2 on 64-bit servers running GemStone/S 64. A makefile and library file for CentOS / Red Hat Linux is included.
Give it a try!
as always, further contributions and enhancements are welcome.
