* pgsql: Fix null-pointer crash in ECPG compiler. @ 2026-06-25 20:58 Tom Lane <tgl@sss.pgh.pa.us> 0 siblings, 0 replies; 2+ messages in thread From: Tom Lane @ 2026-06-25 20:58 UTC (permalink / raw) To: pgsql-committers@lists.postgresql.org Fix null-pointer crash in ECPG compiler. When compiling a DECLARE section containing a union nested inside a struct, ecpg passes a null value for struct_sizeof to ECPGmake_struct_type. I (tgl) didn't foresee that case in commit 0e6060790, and wrote an unprotected mm_strdup() call.
