I'm trying to convert a series of C programs written originally using Informix ESQL to use Postgres' ECPG. ... 575 EXEC SQL connect to pdev_changename; ... I'm using Postgres 8.0.0rc1 on Redhat 9 (kernel 2.4.20-31.9). The same thing happens on fedora core 3, and using Postgres 7.4.6-1.FC3-1.
This also happens with Postgresql 7.4. under SUSE Linux 9.1 (kernel 2.6.4-52) The last version for which embedded SQL worked well for me was 7.3. The same source which worked fine under 7.3 for many months stopped working with my switch to 7.4.2. :-(
And it not only happens during connect, but also during a select. It is very difficult to debug, since often the stack is destroyed and a backtrace in gdb does not work. From what I can see it is always related to calls of malloc/free/realloc issued by libpq.
