Please enter a FULL description of your problem:
------------------------------------------------
Using repalloc in some functions in a shared library I load, the effect is
not the desidered one: the allocated area gets overwritten and causes
segfault once the function returns or calls SPI_finish()




Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
hrm...I noticed some memory areas palloc'ed during a SRF initialization get
overwritten. Also backend tends to crash randomly.
As of now I fixed using palloc/memcpy variant to achieve the same result.




If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------
no clue.
