Bug ID: 69745
Summary: Too big precompiled headers seem to result in a silent
compilation failure
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: pch
Assignee: unassigned at gcc dot gnu.org
Reporter: vz-gcc at zeitlins dot org
Target Milestone: ---
This problem had been previously reported in
https://gcc.gnu.org/ml/gcc-help/2011-12/msg00019.html and also
http://stackoverflow.com/q/21008274/15275 and we've just run into it again:
creating a precompiled header somehow "succeeds" while creating a 0 byte .gch
file and the subsequent compilation using it _silently_ fails, i.e. the
compiler exits with 1 without any error messages, not even when called with
"-v" option.
This was observed using the MinGW-w64 version of gcc (see the full specs
below), but from the URLs given above it doesn't seem to be MinGW-specific, so
I'm reporting it here.
