* [Bug dynamic-link/26728] New: Change _dl_fatal_printf to dump core file @ 2020-10-13 10:09 jg at jguk dot org 2020-10-13 10:16 ` [Bug dynamic-link/26728] " schwab@linux-m68k.org ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: jg at jguk dot org @ 2020-10-13 10:09 UTC (permalink / raw) To: glibc-bugs https://sourceware.org/bugzilla/show_bug.cgi?id=26728 Bug ID: 26728 Summary: Change _dl_fatal_printf to dump core file Product: glibc Version: 2.34 Status: UNCONFIRMED Severity: normal Priority: P2 Component: dynamic-link Assignee: unassigned at sourceware dot org Reporter: jg at jguk dot org Target Milestone: --- Could _dl_fatal_printf be considered to change to call raise a signal that dumps the core instead of _exit(127)? As the code is an assert(), perhaps SIGTRAP or SIGABRT is best? On my computer any C program compiled with assert(0) dumps a core file, but this glibc issue assert does not dump a core file. Inconsistency detected by ld.so: ../elf/dl-tls.c: 481: _dl_allocate_tls_init: Assertion `listp->slotinfo[cnt].gen <= GL(dl_tls_generation)' failed! Command exited with non-zero status 127 This came up while discussing this issue https://sourceware.org/bugzilla/show_bug.cgi?id=19329 This is my test program $ ./a a: a.c:6: main: Assertion `0' failed. Aborted (core dumped) $ cat a.c // gcc -Wall -o a a.c #include <assert.h> int main() { assert(0); } -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
