Abend S0C4 in Logging

[Martin-Zeithaml]

CEE3204S The system detected a protection exception (System Completion Code=0C4).
  From compile unit ZZOW08:/ZOWE/tmp/pax-packaging-configmgr-1726751328246/content/build/../c/logging.c

          0000000037358BBA.

The abend is caused by memcpy for a simple reason: in some cases, the context is NULL, so we are trying to write that eyecatcher to address zero:

MVC      #AddressShadow(8,r6,0),'RSLOGCTX.'(r9,0)

HEAPPOOLS(OFF) and HEAPPOOLS64(OFF)

I have added function ensureLE() to the main. It seems the LAA, LCA and CAA to be fine.

The possible problem remains in safeMalloc31: it could possibly return NULL and there is no check for NULL.

Is this a ticket resolved by The CAA fix?

Interesting that HEAPPOOLS and HEAPPOOLS64 is off. Is that certain? Sometimes it is off in certain areas of the code but not others.

This is happening on the customer's machine and I have sent them configmgr with new debug information, the binary was created from v3.x/staging, which means with -DNEW_CAA_LOCATIONS=1 flag in use.

[Martin-Zeithaml]

@1000TurquoisePogs Customer is using Zowe v3.0.0 - this version is without -DNEW_CAA_LOCATIONS=1, which means the abend is really happening with or without -DNEW_CAA_LOCATIONS=1.

@Martin-Zeithaml, please provide a CEE dump if you have one.

@Martin-Zeithaml , could you ask the customer to capture an SVC dump?

1. Disable the LE error handling

Add export _CEE_RUNOPTS="TRAP(OFF)" to the shell script which executes the configmgr binary.

2. Set a slip trap

Issue the following operator command: SLIP SET,ID=D001,J=ZWE*,COMP=0C4,A=SVCD,SDATA=(ALLNUC,CSA,LPA,PSA,RGN,SQA,SUM,TRT),END

You may want to adjust the job name mask J to match your Zowe/configmgr name. It's likely something different at the customer site.

3. When an SVC dump has been captured, remove the trap

Issue the following operator command: SLIP DEL,ID=D001,END

Hello

Can you please provide the name of the shell script which executes configmgr ?
I suppose I can't put it on the STDENV DD CARD zowe PROCLIB ?
