Bug #: 98
Summary: MinGW: stack trace on exception needs enhanced
Classification: Unclassified
Product: GDC
Version: development
Platform: x86
OS/Version: MinGW
Status: NEW
Severity: minor
Priority: Normal
Component: gdc
AssignedTo: ibuc...@gdcproject.org
ReportedBy: slavo5...@yahoo.com
Daniel Green created an issue 2012-06-12
*****************************************
D introduced a stack trace feature on exceptions. Currently, this will only
list address of the function and no additional information.
This should be enhanced for MinGW 32/64 to return better output for GDC.
The MinGW64 version would also crash upon execution of StackWalk64 after a
Fiber context switch.
This occurred on the first call(suggestive that is a windows issue?) and may
have been related to unapplied Windows Updates.
However, due to the following stack disappearance with GDB this will remain
disabled until it this issue has been resolved or proof that it was a Microsoft
bug.

call stack?
When compared to the values given by StackWalk64. It's missing 4 frames of
stack information lost upon calling rt.dmain2._d_run_main.tryExec. Prior to the
use of Fibers. This symptom was not exhibited by MinGW32.
