Hi David,
Could you please comment out the following line in
$DMTCP_SRC_DIR/mtcp/mtcp_restart_nolibc.c, re-compile, and test:
157 else {
158 if (new_brk == current_brk)
159 MTCP_PRINTF("error: new/current break (%p) != saved break (%p)\n",
160 current_brk, mtcp_saved_break);
161 else
162 MTCP_PRINTF("error: new break (%p) != current break (%p)\n",
163 new_brk, current_brk);
164 // mtcp_abort (); /* COMMENT THIS LINE */
165 }
This should fix the problem without affecting other functionality.
Thanks,
Rohan

How ServiceNow helps IT people transform IT departments:
1. Consolidate legacy IT systems to a single system of record for IT
2. Standardize and globalize service processes across IT
3. Implement zero-touch automation to replace manual, redundant tasks
