Informix Error -1101: Variable address is NULL.

Reasons / Common Causes

-1101 is flagged by the official text as an internal error — the program passed a NULL variable address into a routine that requires a valid one, a condition the official guidance doesn't attribute to any specific, named application-level trigger.

1. A genuine internal condition, per the official guidance's framing — no other documented application-level cause is named.
2. A runtime library or environment inconsistency that leaves an internal variable-address reference unset, a plausible contributor given the bare "internal error" framing, though not explicitly named by the sparse official text.

Solutions / Resolution

1. Note all circumstances and contact IBM Informix Technical Support, per the official guidance — this is the documented, only resolution path for an internal error of this kind.
2. Capture the exact operation being performed when this occurred, since the official guidance gives no other diagnostic detail to narrow the cause further.
