Bug ID: 67680
Summary: Seg Fault in gcc 4.9.3 compiling
libiberty/floatformat.c when building gcc 5.2.1 on
Cygwin 64 on Windows
Product: gcc
Version: 4.9.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: bplummer at hotmail dot com
Target Milestone: ---
both the configure and the make args were default. I've tried a wide variety
of args for both configure and make and the error is blindingly consistent.
Here are the details :
