I get a reduced test case for this bug. Attached here. segv fault is cause by following code snip in cp/mangle.c static tree mangle_decl_string (const tree decl) { ... input_location = DECL_SOURCE_LOCATION (decl); // input_location is ZERO ... write_mangled_name (decl, true); // Segv fault is triggers in child calls. } This piece of code is backported from gcc 4.5 to fix GCC PR42748, http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42748 The decl is __PRETTY_FUNCTION__, and input_location on FSF 4.5 is NOT zero.DECL_SOURCE_LOCATION should return non-zero value for __PRETTY_FUNCTION__, so that it could be mangled.

[Bug 635199] Re: [armel] the ./H5detect test segfaults when built for armv7
It is not a toolchain issue here. In H5detect.c:ALIGNMENT, a testing to mis-aligned access is performed, as below, *((TYPE*)(_buf+align_g[_ano])) = _val; /*possible SIGBUS or SEGSEGV*/ \ _val2 = *((TYPE*)(_buf+align_g[_ano])); /*possible SIGBUS or SEGSEGV*/ \ and SIGBUS and SIGSEGV is handled. However, on ARM, at least in thumb2, SIGILL is generated. This can be verified by this small case, int main() { char c[20]; int i =0; float f; for (i = 0; i < 4; i++) { printf ("address is %x\n", (unsigned int) &c[i]); f = *((float*) &c[i]); } return 0; } $ gcc align.c -o align $ ./align address is be8ebc20 address is be8ebc21 Illegal instruction However, everything is OK with -march=armv5t, $ gcc -march=armv5t align.c -o align $ ./align address is bedfbc20 address is bedfbc21 address is bedfbc22 address is bedfbc23 To fix this problem here, we may can either modify source code of hdf5 to handle SIGILL, or change kernel to use SIGBUS for unalinged access instead of SIGILL (http://www.spinics.net/lists/arm- kernel/msg93601.html). -- [armel] the ./H5detect test segfaults when built for armv7 https://bugs.launchpad.net/bugs/635199 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 636229] Re: armel build failure (armv7 specific?)
Reduced test case to gcc is here, void coq_interprete() { register int accu asm("r7"); accu = 0; } # gcc-4.5 -S /home/yao/test.c /home/yao/test.c: In function 'coq_interprete': /home/yao/test.c:6: error: r7 cannot be used in asm here No error if compiled with -fomit-frame-pointer # gcc-4.5 -fomit-frame-pointer -S /home/yao/test.c In thumb mode, r7 is used as frame pointer register.
