Hi, I have a problem with GCC 7.3.0 (problem is in all versions) and precompiled headers. I have the sample file http://ge.tt/7fRLk1t2 which causes Segmentation fault in cc1. The test passes normally on Linux. I searched why and found that the result here https://github.com/gcc-mirror/gcc/blob/gcc-7_3_0-release/gcc/ggc-common.c#L626 is 1 in Linux and -1 in CygWin.
In Linux the method called is https://github.com/gcc-mirror/gcc/blob/gcc-7_3_0-release/gcc/config/host-linux.c#L182 In Cygwin the method called is https://github.com/gcc-mirror/gcc/blob/gcc-7_3_0-release/gcc/ggc-common.c#L708 - mmap return address is not equal to base address. There are also some reports in gcc bugzilla.
