[Bug binutils/29389] Failed assertions in bfd/cofflink.c and bfd/coff-x86_64.c during the linking stage (MSYS2 MinGW64)
https://sourceware.org/bugzilla/show_bug.cgi?id=29389 --- Comment #15 from Luca Bacci --- Uh...how strange! One of the very first things that _bfd_coff_link_input_bfd() does is call obj_coff_external_syms() which seeks into the lib file and reads the external symbols table. When _bfd_coff_link_input_bfd() is run with input_bfd->filename == "libgobject_2_0_0_dll_d000431.o" for the second time, obj_coff_external_syms() is executed, which calls cache_bseek() (then _bfd_real_fseek(), then fseeko64()) with an offset of 73060, on both Linux and MSYS2. However, on Linux the read buffer is: (gdb) p abfd->where $19 = 73060 (gdb) p result $20 = 0 (gdb) n 405 in /usr/src/debug/binutils-2.38/bfd/bfdio.c (gdb) _bfd_coff_get_external_symbols (abfd=0x5bc67750) at /usr/src/debug/binutils-2.38/bfd/coffgen.c:1692 1692/usr/src/debug/binutils-2.38/bfd/coffgen.c: File o directory non esistente.

[Bug binutils/29435] Building openblas with binutils 2.38 leads to "ELF load command address/offset not properly aligned"
https://sourceware.org/bugzilla/show_bug.cgi?id=29435 --- Comment #1 from Francois-Xavier Coudert --- How to reproduce: 1. Download and extract OpenBLAS-0.3.20 from https://github.com/xianyi/OpenBLAS/archive/v0.3.20.tar.gz 2. Run: $ DYNAMIC_ARCH=1 TARGET=CORE2 make libs netlib shared 3. Create a test.c file: $ cat test.c #include #include #include #include "cblas.h" int main(void) { int i; double A[6] = {1.0, 2.0, 1.0, -3.0, 4.0, -1.0}; double B[6] = {1.0, 2.0, 1.0, -3.0, 4.0, -1.0}; double C[9] = {.5, .5, .5, .5, .5, .5, .5, .5, .5}; cblas_dgemm(CblasColMajor, CblasNoTrans, CblasTrans, 3, 3, 2, 1, A, 3, B, 3, 2, C, 3); for (i = 0; i < 9; i++) printf("%lf ", C[i]); printf("\\n"); if (fabs(C[0]-11) > 1.e-5) abort(); if (fabs(C[4]-21) > 1.e-5) abort(); return 0; } 4. Compile and run: $ gcc test.c -I ./build2 -L ./build2 -lopenblas -pthread && ./a.out ./a.out: error while loading shared libraries: libopenblas.so.0: cannot open shared object file: No such file or directory PS: If Openblas is built without DYNAMIC_ARCH=1, then the library produced works. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug binutils/29389] Failed assertions in bfd/cofflink.c and bfd/coff-x86_64.c during the linking stage (MSYS2 MinGW64)
https://sourceware.org/bugzilla/show_bug.cgi?id=29389 --- Comment #16 from Luca Bacci --- On MSYS2, bfd/cache.c:bfd_cache_max_open() returns 10, while on Linux it returns 128 (because HAVE_GETRLIMIT is defined) If I force the cache size on MSYS2 to a higher value, e.g. 500, then the issue goes away. On the countrary, if I set the cache size to 10 on Linux, then I can successfully reproduce the issue (using the instructions in https://sourceware.org/bugzilla/show_bug.cgi?id=29389#c11) Hope it helps!
