Hello, I am facing a strange problem while running a SAC Macro. The output
is correct and the macro is performing but showing the strange error.

----------------------------------------------------------------------------------------------------
**The Macro is:*
r $dat
evaluate to tstart &1,dist / 8.
evaluate to tdeb &1,dist / 3.0
evaluate to tfin %tdeb + 201
if &1,delta gt 1
evaluate to tadd &1,delta * 201
evaluate to tfin %tdeb + %tadd + 10
endif
evaluate to tbid &1,dist / 2.5
if %tbid gt %tfin
evaluate to tfin %tbid
endif
cut %tstart %tfin

Dear Shantanu,
Quickly: version 101.3b has this specific bug fixed. Please consider
upgrading to the newer version.
I tracked down this issue in version 101.2. The error you are seeing
is due to your current, or system's default value, of the environment
variable MALLOC_CHECK_ and a buffer overrun bug in version 101.2.
The possible settings for MALLOC_CHECK_:
0 = no error, do not abort
1 = show error, do not abort
2 = no error, abort
3 = show error, abort
You probably have the setting set at 1. This is the reason you are
seeing an error, but the program continues and does not abort.
Version 101.3b has fixed this specific bug and I would suggest that
you upgrade to this version.
