New issue 5933 by craig.schlenter: test_shell_tests aborts due to double free on linux with hammer SHARED=1 http://code.google.com/p/chromium/issues/detail?id=5933 glibc is picking up a double free when running test_shell_tests on linux for rev 7526 of trunk. This is only happening when compiled with SHARED=1. Here's the tail end of the output ... 7 FAILED TESTS Leak 1 JS wrappers. *** glibc detected *** Hammer/test_shell_tests: double free or corruption (!prev): 0x09129678 *** ======= Backtrace: ========= /lib/libc.so.6[0xc41874] /lib/libc.so.6(cfree+0x96)[0xc438d6] Hammer/test_shell_tests(_ZN2v88internal8Malloced6DeleteEPv+0x11)[0x8147b95] Hammer/test_shell_tests(_ZN2v88internal4ListIiNS0_25FreeStoreAllocationPolicyEED1Ev+0x25)[0x816f44d] /lib/libc.so.6(__cxa_finalize+0xc1)[0xc01e91] /home/craig/chromium/src/webkit/Hammer/dbg/lib/libtest_shell.so[0x2966b44] /home/craig/chromium/src/webkit/Hammer/dbg/lib/libtest_shell.so[0x2b20fc0] /lib/ld-linux.so.2[0xdb1f7b] /lib/libc.so.6(exit+0x89)[0xc01b39] /lib/libc.so.6(__libc_start_main+0xee)[0xbea5de] Hammer/test_shell_tests(_ZNSsD1Ev+0x65)[0x8104341] ======= Memory map: ======== [snip] What seems to be happening is that when libtest_shell.so is unloaded __cxa_finalize and exit both seem to be trying to free some v8 data. The actual problem appears to be that libtest_shell.so is linked against v8 which is unnecessary. Only test_shell_tests should be linked to v8. I'm attaching an ugly patch that does this but there is probably a nice way of doing this and I'm unsure of the implications for other platforms. Perhaps this can be assigned to evmar or sgk to fix properly please?
