Hi,
I am trying to use V8 as a way to call a js program from C++, however there
is an issue that I don't really know how to debug.
When I try to use *gdb* I get nothing but assembly code from the V8 side, I
do have the *is_debug=true* flag, but it seems that it doesn't control
whether C++ code is available or not like *-g* would when calling the
compiler directly.
As for the program, if anyone has any insight, it's a parser, when the text
to parse is one token only, I get an AST out, if is more than one, say *3 +
2*, calling it via node works fine (I get a similarly looking AST, just
with more nodes) but via V8 I get this error:
```
#
# Fatal error in ../../src/objects/intl-objects.cc, line 2478
# Debug check failed: U_SUCCESS(status).
#
#
#
#FailureMessage Object: 0x7ffc0cb58460

```
I am using V8 9.7.106.18, so I followed down to where the error was coming
from in the right version here
<https://chromium.googlesource.com/v8/v8/+/refs/tags/9.7.106.18/src/objects/intl-objects.cc#2478>,
but it didn't give me any specific insights into what the problem might be
other than it having something to do with ICU and Unicode. It was at this
point I tried gdb, but as mentioned above I couldn't get a step by on the
V8 code side.
Any suggestions for how one might go about dubbing such an issue?
