--- Comment #6 from Gerald Pfeifer <gerald at pfeifer dot com> --- (In reply to Gerald Pfeifer from comment #4) > Let me change gcc/cp/module.cc as follows > > -#ifndef HAVE_POSIX_FALLOCATE > #define posix_fallocate(fd,off,len) ftruncate (fd, off + len) > -#endif > > for my nightly builder. (Setting to NEW since Lorenzo confirmed.) Success! Comparing the results from 2024-12-18 https://gcc.gnu.org/pipermail/gcc-testresults/2024-December/833176.html with those from 2024-12-20 https://gcc.gnu.org/pipermail/gcc-testresults/2024-December/833310.html the size of testsuite output went from 1+MB to 171kB. Nathaniel, is there any chance you can use this to tweak the code? (Simply using ftruncate instead of posix_fallocate is not an option, I guess?)
