Bug ID: 97217
Summary: C++ program compiled with GCC crashes
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: carsten.schmidt-achim at gmx dot de
Target Milestone: ---
Created attachment 49277
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49277&action=edit
Example assembly listing causing the crash.
During development of my vector/matrix library using template meta programming,
I discovered that my test program crashes on some occasions when being compiled
with GCC.
When inspecting the assembly code generated by GCC, the instruction crashing
the program
seems to be unrelated to the data flow of the program.
I will attach the generated assembly of one of my test cases, which crashes the
program.
Please let me know if you would like to investigate further and how I can be of
service!
