Bug ID: 118495
Summary: Unable to build gdc (D compiler) for MinGW-w64
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: brechtsanders at users dot sourceforge.net
Target Milestone: ---
I have been attempting to nateveliy build the gdc D compiler on Windows
MinGW-w64.
The last build with where D language and libphobos didn't fail was GCC11.
So I am now using a GCC11 I build to attempt a GCC15 snapshot build.
But this keeps crashing on d21.exe.
Any idea how to solve this?
