[jira] Commented: (HARMONY-5297) [drlvm][signals] It would be very helpful if crash handler printed VM memory map, command line arguments and OS environment

Alexey Varlamov commented on HARMONY-5297:
------------------------------------------

Another possible improvement, print names of generated stubs in stack trace of crash dump:
stack_dump.cpp: fprintf(stderr, "%3d: 0x%"W_PI_FMT"  <Generated stub>\n",
AFAIK this info is available for free, you just need to add it to print.

> Often when VM crashes, especially in CC batch runs it isn't possible to recognize how VM was launched and in which environment. Keeping command line arguments used for JN_CreateJavaVM and then printing them at the crash point would be really helpful.
> Also additional information like OS environment and modules mapping would be helpful too.
