Bug ID: 112828
Summary: Abort with malloc(): corrupted top size
Product: gcc
Version: 13.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran

MWE demonstrating problem
When I compile the attached MWE with
gfortran -o test test.f90
...I get the following runtime error:
malloc(): corrupted top size
Program received signal SIGABRT: Process abort signal.
Backtrace for this error:

Aborted
If I comment out the first allocate statement (the one with the STAT argument),
then the program runs without problem (even though this statement isn't
actually executed). There are a number of other things that make the bug go
away; e.g., shrinking the length of the character variables in the main program
to 20 or smaller. Setting the length to 21 still runs without error, but the
second element of c_r ends up with some junk in it, viz:
foo foo A
